10 things you need to ask yourself if you are thinking about having sex

Posted by Unknown Friday, January 25, 2013 0 comments
10 things you need to ask yourself if you are thinking about having sex ~  Most people have sex for the first time when they're 16 or older, not before. If someone’s boasting about having sex, it’s possible that they’re pretending. 

Although there's a legal age of consent, it’s not necessarily the right age for you to start having sex. There are no rules about how long you have to be going out with someone before you do it. Being ready happens at different times for everyone – don't decide to have sex just because your friends are pressuring you. You can read this whole page or go straight to the sections: 

It's your decision

You can always choose whether you want to have sex, whoever you're with. Just because you've done it before, even with the same person, doesn’t mean that you have to do it again. 
Working out whether you're ready is one of life’s big decisions. You're the only one who can, and should, decide. Whether you're thinking about losing your virginity or having sex again, remember the following tips.

Talking about sex

It’s better to have an embarrassing talk about sex than an embarrassing sexual encounter before you’re ready. There are lots of things to think and talk about, such as:
  • are you both ready?
  • will you be having sex for the right reasons and not because of peer pressure?
Sex isn’t the only aspect of a relationship, and there are other ways of enjoying each other’s company. Discuss what you want and what you don’t want to do. You can do other things that you both like, such as talking, meeting each other’s family and friends, going to gigs or the cinema, doing sport, walking, and listening to music. 

10 questions to ask yourself

You need to have the confidence to work out how you want to respond if sex comes up, and how far to go. Ask yourself if you feel comfortable. Is it the right time, in the right place, and with the right person? Do you really trust the person, and do you feel the same way about one another?
If you think you might have sex, ask yourself the following questions:
  • Does it feel right?
  • Do I love my partner?
  • Does he/she love me just as much?
  • Have we talked about using condoms, and was the talk OK?
  • Have we got contraception organised to protect against pregnancy? 
  • Do I feel able to say ‘no’ at any point if I change my mind, and will we both be OK with that?
If you answer yes to all these questions, the time may be right. But if you answer yes to any of the following questions, it might not be:
  • Do I feel under pressure from anyone, such as my partner or friends?
  • Could I have any regrets afterwards?
  • Am I thinking about having sex just to impress my friends or keep up with them? 
  • Am I thinking about having sex in order to keep my partner?
Being in a relationship doesn’t mean you have to have sex. Even if you’ve done it once or twice you still need to make sure that your boyfriend or girlfriend is as keen as you each time. 

Safer sex

When you decide to have sex, there's the possibility of pregnancy and/or catching a sexually transmitted infection (STI) such as chlamydia. Whoever you're thinking of having sex with, it's important to talk about contraception and condoms before you have sex. Both of you have a responsibility to have this conversation. 

Condoms

You need to use condoms to reduce the risk of catching an STI, whoever you are having sex with. If you're a boy/girl couple, you need to use an additional form of contraception to prevent an unintended pregnancy. 

Contraception

There are 15 different kinds of contraception, including the implant, injection, the combined pill and the progestogen-only pill. Most kinds of contraception are used by girls, but both of you have a responsibility to consider which you will use. A pregnancy will affect both of you. 

Lesbian, gay or bisexual couples

If you have lesbian, gay or bisexual sex you can still get or pass on STIs. You still need to know about contraception in case you have straight sex as well. Find out more about sexual health for women who have sex with women and for men who have sex with men.

How do I bring up the subject of safer sex?

Starting a conversation about the different types of contraception could be a good way to start talking about other issues to do with sex, such as how you feel about it and what you do and don’t want to do. You could try saying, "I found out that there are 15 different types of contraception…If we were to have sex, which one should we use?"
And researching the options together will help both of you feel more confident and in control of the situation. Find out about the 15 different kinds of contraception. 

You can get free and confidential advice about sex, contraception and abortion at any time. Visit your local doctor, community contraceptive clinic, sexual health or genitourinary medicine (GUM) clinic (find your local services) or young persons clinic (call 0800 567 123) to find out more. 

Read the signs that they want sex

Many people are surprised when a situation leads to sex, so learn to read the signs. If someone suggests that you find a quiet place, or makes lots of physcial contact, or suddenly tries to charm and flatter you, they might be thinking about sex, even if you’re not.
You need to decide whether you want to have sex. Don’t let someone else decide for you by just going along with it. Make the decision in advance and stay in control of the situation, especially if you've had alcohol, because you'll be less inhibited.
If you’re not sure that you can stay in control, avoid situations that could lead to sex, such as going to someone’s room or somewhere quiet. 

Alcohol or drugs won't help

Many people have sex or lose their virginity when they’re drunk. After a few drinks, you're more likely to lose your judgement, and you may do things that you wouldn't do normally. You may regret your actions in the morning, and you won't be able to undo what you’ve done.
People are more likely to have sex without a condom when they're drunk. This can lead to an STI or unintended pregnancy.
Find out more about sex, alcohol and keeping safe.

Sex and the law

The law says that it's legal for you to consent (agree) to sex from the age of 16. If you're under 16, you can get confidential contraceptive and sexual health services, including abortions. You can get free condoms from some GPs, community contraceptive or young persons clinics, and Brook Advisory Centres.
If you're under 13, the situation is different because the law says that you can’t consent to sex at this age.

Fish oil prevents death from a heart attack?

Posted by Unknown 0 comments
Fish oil prevents death from a heart attack? ~ Why fish oils hold all-powerful key to healthy heart’ is the headline in the Daily Express, which goes on to report, somewhat over-enthusiastically, that ‘tens of thousands of lives a year could be saved if people ate more fish’.

These wildly optimistic claims are actually based on an small experimental study involving 59 people, looking whether our genetic makeup affects how dietary fats can influence the way in which our blood vessels constrict (narrow) and dilate (widen). The question of whether eating fish gives us a healthy heart, or saves lives, was not considered by the researchers.

On two separate occasions the participants were given either a drink high in saturated fats, or a drink with some saturated fats combined with fish oils.
The researchers then used ultrasound to look at how their subjects’ blood vessels dilatated again after being briefly blocked by a blood pressure cuff. 

In general, the researchers found that the response of the blood vessels varied:
  • according to the drink given
  • between men and women
  • between people with the two different gene types known to affect blood vessel dilation
There was greater blood vessel dilatation after the drink that contained the fish oils was consumed, particularly in women with a gene type known as Asp298, which is thought to apply to around 10% of the population.

Very limited conclusions can be drawn from this study due to its size.
A healthy balanced diet and regular exercise are known to be key to good health. Whether fish oils have any particular effect on heart health cannot be answered by this study.

Where did the story come from?

Researchers from the University of Reading conducted this research which was published in the Journal of Lipid Research. Funding was provided by the Biotechnology and Biological Sciences Research Council, Unilever PLC, and FRST – Foundation for Research, Science and Technology (New Zealand). The saturated fat (palm stearin) used in the study was donated by Aarhuskarlshman, UK and the fish oil by Croda Healthcare, UK.

The media has greatly overestimated the implications of this small experimental study which did not specifically aim to assess whether fish oils affect heart or vascular health (the health of blood vessels). Instead, it aimed to look at whether a person’s genetic makeup affects how their blood vessels respond to dietary fats.

It appears that the media’s reporting of the story has been influenced by a number of quotes from one of the lead researchers, Professor Christine Williams, who made the case that fish oil could widen the blood vessels that supply blood to the heart. This in turn, could help prevent heart attacks (heart attacks are triggered when the muscles that make up the heart are starved of blood).

However, this is due to a process of atherosclerosis, where the blood vessels become clogged due to a build up cholesterol and other fatty deposits – it is not directly linked to the temporary constriction and dilation of blood vessels as this study observed.
It is a gross extrapolation of the data presented in the study to claim that ‘tens of thousands of lives a year could be saved if people ate more fish’.

What kind of research was this?

The researchers describe that reduced blood vessel reactivity – how they constrict and dilate – is an early modifiable step in the development of atherosclerosis – the thickening of the arteries due to build-up of fatty deposits. They say that there is increasing evidence that dietary factors can have an effect on blood vessel reactivity, and that dietary fat in particular may be an important modulator. Long-chain polyunsaturated fatty acids (PUFA) are particularly supposed to have beneficial effects. These fatty acids include omega-3 fatty acids, which are found in fish oils and some plant sources. 

The fatty acids are believed to have a possible effect on the chemical nitrous oxide, which causes blood vessels to dilate. Nitrous oxide is produced by the cells lining the blood vessels using an enzyme called endothelial nitric oxide synthase (eNOS).
This experimental study aimed to see whether variations in the eNOS gene have an effect on how blood vessels respond to fat in the diet. It did this by looking at what happened when people with different forms of the eNOS gene were given either saturated fats or PUFA. It did not aim to look at the long term effects of fatty acids on blood vessels or the heart.

What did the research involve?

The researchers recruited:
  • 29 people who had two copies of the Asp298 variant (form) of the eNOS gene (each person carried two copies of each gene – one from each parent)
  • 30 people who had two copies of the Glu298 variant of the eNOS gene (the more common type)
All the adults were healthy non-smokers, aged 18-65 with body mass index (BMI) from 18-32, and had no cardiovascular diseases or metabolic diseases and weren’t taking medications that could affect blood clotting or blood pressure. All of their blood fats were in the normal range. 

Participants attended the study centre on two separate occasions. On one occasion they received a test drink high in saturated fats (0.52g/kg body weight), and on the other they received a drink with the same total amount of fat, but made up of a combination of saturated fats (0.45g/kg body weight) and PUFA (0.07g/kg body weight). 

As an example the researchers say:
“A 70kg individual would therefore receive 36.4g palm stearin; or 31.5g palm stearin and 4.9g of fish oil concentrate, which contained 3.8g docosahexaenoic acid (DHA) and 0.4g eicosapentaenoic acid (EPA) (equivalent to 1.5 times a standard 140g portion of oily fish).”

The drinks were consumed over 240 minutes and were identical in protein and carbohydrate content.
Before and after taking the drinks, the participants had blood tests taken, and various measures of vascular reactivity were measured using ultrasound. This included measuring flow-mediated dilatation, where a blood pressure cuff was inflated to temporarily occlude (block) the blood vessels.  The cuff was then rapidly released to see how fast the blood vessel responds by returning to its original shape.

What were the basic results?

Before the start of the experiment, the researchers found that the people with the two different forms of the eNOS gene in the study were fairly similar. An exception to this was women with two Asp298 gene variants (genetic variants are often referred to as alleles). In these women it was found that they had both higher blood levels of fatty acids and higher flow-mediated dilatation (their blood vessels responded more quickly in returning to normal and allowing blood to flow after the cuff was removed). 

The researchers found that there were differences in flow-mediated dilatation in response to the two fat drinks, with responses differing according to gender, and according to gene type. Following the saturated fat drinks there was a decrease in flow-mediated dilatation, and this was similar in both men and women. Following the drink of saturated fat combined with PUFA, there was an increase in flow-mediated dilatation, with women having greater increases than men. 

Generally, the response was fairly similar for the people with the two different eNOS gene types – those with two Asp298 alleles and those with two Glu298 alleles. However, those with the less common Asp298 alleles showed greater differences in their flow-mediated dilatation when given the two different drinks.

How did the researchers interpret the results?

The researchers conclude that dietary fatty acids have an effect on the dilation of blood vessels, and that the effects of eating different compositions of fats appears to be dependent on both the type of eNOS gene, and gender. The greatest difference in vascular response to two fat loads was in women with two Asp298 variants of the eNOS gene.

Conclusion

The media has taken the implications of this experimental study a little too far. The study found differences in the dilatation of the blood vessels depending on type of fatty acids consumed, the person’s gender, and what form of the eNOS gene a person had. However, this was a very small study involving only 29 people with one form of the gene and 30 with another.

The study cannot tell us whether the changes seen would persist in the long term if a person followed a diet high in fish oils. Most importantly, it also doesn’t tell us whether the small changes in blood vessel flow would have any effect at all on the cardiovascular health of the person.

A healthy balanced diet and regular exercise are known to be key to good health.
Whether fish oils have any particular effect on heart health cannot be answered by this study.

So despite any claims, taking fish oil supplements alone, without improving your diet or increasing your levels of exercise, is not going to give you a short-cut to a healthy heart.

Use Condom During Sex 'Just as Good'

Posted by Unknown 1 comments
Use Condom During Sex 'Just as Good' ~ "Men and women enjoy sex just as much with condoms as they do without," the Daily Mail was delighted to report, covering a US study that appears to contradict one of the classic male excuses for not using a condom – "I lose sensitivity". 

The study involved a survey of 1,645 men and women aged 18 to 59 in the US who were questioned about their use of condoms and lubricants during their most recent sexual encounter. The focus of the study was male-female penile-vaginal intercourse.
In particular, the study looked at whether condom use is related to how people rated their enjoyment of sex. The study found that there was no difference in how easily men achieved an erection if they used condoms compared with men who didn't use condoms.

Condom use also did not make a significant difference to whether couples rated their sex as arousing and pleasurable. The study also looked at the use of lubricants and how much people knew about them. The researchers found a worrying lack of knowledge among women about the lubricant that they had used during intercourse. This is important, as some types of oil-based lubricants can damage latex condoms, making them more likely to split. 

The results of this study appear to overturn the belief that condoms can interfere with sexual pleasure, which is good news. Condoms may not be the most romantic or arousing thing in the world, but compared with an unwanted pregnancy or sexually transmitted infection (STI), they are up there with roses and champagne.

Where did the story come from?

The research was carried out by researchers from Indiana University, US.  It was funded by Church & Dwight Co Inc, the maker of Trojan Brand Condoms, a leading brand of condoms in the US. 

This arguably represents a potential conflict of interest, although there is no evidence that the results of the study were manipulated in any way.
The study was published in the peer-reviewed Journal of Sexual Medicine. The Daily Mail reported the study uncritically, including comments comparing it with the famous Kinsey reports on human sexual behaviour, which is a little over the top. The Kinsey reports took several decades to complete and involved personal interviews with thousands of people. 

Also, possibly due to its target audience, no mention was made of the fact that the study's findings may not apply to other sexual practices, such as anal or oral sex.

What kind of research was this?

The data used in the study was taken from a national cross-sectional survey of sexual health and behaviour carried out in the US in 2009. This particular study aimed to look at the use of condoms and lubricants during the participants' most recent sexual event, and whether condom use was associated with how they rated this experience in terms of quality.

The authors say that more information is needed about whether the experience of sexual events is influenced by the use of condoms and/or lubricants.
They say that lubricant use among women and male-female couples is particularly poorly understood. Much of the literature about the use of lubricants covers men who have sex with men. 

Little is known about the situations where lubricants, or condom and lubricants, are used, or how people feel about these. This study is useful in that it informs us about the sexual health behaviour of a reasonably large group of US adults, covering their most recent sexual encounter and how pleasurable it was, but it tells us little more than that.

What did the research involve?

The researchers used data from a national survey of sexual health and behaviour. This involved an online questionnaire given to a nationally representative sample of US adults. The sampling frame the adults were recruited from was said to have captured 98% of all US households. Of the 6,182 adults invited to participate, 5,045 (82%) took part. 

For this particular study, participants were asked to report on their most recent sexual event with a partner in the past year, and the sexual behaviour associated with this event (such as giving or receiving oral sex, vaginal intercourse, receptive or insertive anal intercourse). They were also asked about their partner's gender and their relationship with their partner (spouse, girlfriend/boyfriend, friend, or transactional sex partner).

They were asked whether they had used a condom and if so, what type (such as latex or polyurethane) and if the condom was lubricated or not. They were also asked if lubricant was used and if so, which type of lubricant and where it was applied.

Participants were also asked to rate their most recent sexual event in terms of pleasure, arousal and orgasm (their own and their partner's), as well as difficulties with pain or lubrication and erection. Pleasure, arousal, pain and lubrication difficulties were assessed using a five-point scale from 'not at all' to 'extremely'. Orgasm was assessed using three options: orgasm, no orgasm and unsure.

For the purposes of this study, only people aged between 18 and 59 who reported penile-vaginal intercourse at their last sexual event were included in the analysis. They numbered 1,645.

What were the basic results?

The sample was largely white, heterosexual and in very good or excellent health. Most reported a recent sexual event with a relationship partner (56% men, 54% women) or a casual/dating partner (21% men, 27% women). Almost half the participants (48%) indicated they were currently married, while a further 27% indicated they had never been married.

During their most recent sexual experience:
  • 27.5% of men (237) and 22.3% of women (175) reported using a condom
  • more than twice as many women as men were unsure whether the condom was lubricated (26.6% vs 11.4%) and what material it was made of (23.6% vs 8.9%)
  • participants consistently rated sex as arousing and pleasurable regardless of whether they used condoms or lubricant
  • no significant differences were found in men's ratings of the ease of maintaining their erection based on condom and lubricant use
  • men who had sex without a condom or lubricant reported significantly greater arousal than men who used a condom without lubricant
  • the arousal of men who had sex without a condom or lubricant was no different from men who used a lubricant with or without a condom
  • overall, women reported lower arousal rates than men during their last sexual encounter


How did the researchers interpret the results?

The researchers say that despite common myths that suggest condoms make sex less pleasurable, condom and lubricant use are not associated with lower ratings of sexual enjoyment.

Women reported more often than men that they were unsure about the type of condom and lubricant used. This has important implications for health education, as some types of lubricants (oil-based) should not be used with certain types of condoms (such as latex).

Conclusion

Overall, most of the results of this survey appear to undermine the widespread belief that condoms can interfere with sexual pleasure. This is good news, as using condoms can protect against sexually transmitted infection (STI) as well as unwanted pregnancy

It is important to note, however, that all this study can do is provide a limited snapshot of sexual behaviour based on an online questionnaire about one sexual encounter. The sample from which the US adults were recruited was reasonably large and appears to have been nationally representative, although it was limited to adults aged 18 to 59 and was a predominantly white, heterosexual sample. 

It is also important to note that the results are only based on people who reported having penile-vaginal intercourse in their last 'event', and not those who reported same-sex encounters. 

The study also found that a large majority of men and women did not use condoms in their most recent sexual encounter. The study does not tell us why this might be, or whether men and women who did not use condoms were in long-term relationships or using other methods of contraception. 

Overall, this study simply informs us of the sexual behaviour of a group of US adults during their last sexual encounter. The sexual health message remains the same: condoms are one of the best ways of protecting against STIs and unwanted pregnancy.

Some Types of Heart Disease

Posted by Unknown Thursday, January 24, 2013 2 comments


Some Types of Heart Disease ~ Cardiovascular disease refers to diseases that attack the heart and vascular system. The heart is a strategic organ in one's body for his role as the blood pumping.

There are many causes of heart disease such as life style, congenital disorders, and unhealthy diet. A heart attack is a result of the deadly coronary heart disease who became a killer of women and men most in America. In fact, heart disease not only attacks the elderly. Today, many young people who have suffered from various heart diseases. Even newborns can suffer from abnormalities of the heart.

There are 50 more types of heart disease that lurks those with lifestyle and unhealthy eating. Although there are various ways to deal with heart disease, from medical to herbal, prevention is better than cure. Here it is the types of heart disease that you must be aware of.

  • Heart Failure

Heart Failure or Heart Failure is a condition in which the heart can not supply blood flow to meet the body's needs, and potentially lethal. Sometimes heart failure is often mistaken for a heart attack.

This type of heart disease has symptoms include: swelling of the feet and hands, the addition or subtraction of weight before swelling due to excess fluid, shortness of breath, constant fatigue, angina or discomfort in the chest and arms due to blockage of the coronary arteries.

  • Heart Valve Disease

Heart Valve Disease or heart valve problems is a condition in which one or more heart valves do not work properly. In some cases, people are born with heart valve problems, while some people find abnormalities in the valves in his lifetime. Abnormalities of the heart valves can be caused by infection, age, and other illnesses. Almost no symptoms found by people with disorders of the heart valves.

There are three types of heart valve disease: leakage, stricture, and valves without holes. There is no cure for disorders of the heart valves except surgery. But for those of you who do not have the disease from birth, to maintain your diet and lifestyle is the key to be free from this disease.

  • Arrhythmias

It is a kind of disease that interferes with the heart rhythm disorders or heart rate. The heart rate can be faster, slower, and irregular. The main factor is the lack of calcium arrhythmia disease in the body and the heart blood vessel blockage.

Blockage of the coronary arteries also have an effect on heart rate is not normal will result in a heart attack. In addition to these 2 other arrhythmia causes are diabetes, high blood pressure, smoking, caffeine, alcohol, stress, death of heart muscle, drug abuse, and overly active thyroid gland.

  • Pericarditis

Types of heart disease is inflammation of the heart or pericardium sac causing fluid retention and thickening. The inflammation is caused by several things. A common cause is a viral infection and radiation therapy for breast cancer.

Symptoms resulting from pericarditis is shortness of breath, cough, high blood pressure, and fatigue due to the heart becomes less efficient. Heart disease can be diagnosed through MRI or cardiac catheterization. Taking medication to reduce fluid can help reduce the symptoms of pericarditis but total healing done by lifting the pericardium.

  • Coronary Heart Disease

Coronary heart disease is caused by a layer of fat or cholesterol in the walls of arteries that clog arteries. As a result of blockage by a layer of fat and cholesterol is the disruption of the blood supply to and from the heart.

When blood is blocked due to the layer of fat that is called a heart attack. Layers of fat and cholesterol in the artery wall caused by cigarette addiction, hypertension, and high cholesterol.

If someone experience symptoms such as pain in the center of the chest that radiates to the left arm and neck and even down to the back, sweating, and nausea mean the person is likely to suffer from coronary heart disease. For this type of coronary heart disease can be treated with herbs that have been clinically tested and tested by scientists and doctors usefulness. 

There are many heart diseases are not described here. But the most common diseases of the heart at the top. Be aware of the symptoms and always consult your doctor if any of the above heart disease attack you.

Anatomical structure of the heart

Posted by Unknown 1 comments
The outer surface of the heart

1. Pericardium
Heart in the sheath by a membrane called the pericardium lining the inside of the heart wrapping sticking very closely to the heart, while the outer layer more loose and watery, to avoid friction between the organs in the body that occurs due to the movement of the heart's pumping.

2. Heart Muscle
For the heart to function as an efficient pump, the heart muscles, upper cavity and bottom cavity must contract in turn. The heart has begun to beat the time in the womb and will never stop until our last breath.

The heart is the most amazing organ because of the relentless pumping oxygenated blood and nutrients in the blood throughout the body. The heart beats 100 thousand times per day, or about 2000 gallons of blood pumped per day. The heart is a muscle in the body turned out to be the most hard working, and the strongest. Heart wall is composed of three layers, from the inside consists of

  • Endocardium is the innermost layer of the heart is an endothelial layer that continues into the arteries and veins.
  • Myocardium is the muscular part of the heart terususn the heart muscle (myocardial). The heart muscles to contract and pump blood through the arteries.

  • Epicardium or the so-called "pericardium viscerais" is the outermost part of the heart is composed of connective tissue.
The outer surface of the human heart and vascular rear

Chambers of the heart
human heart is divided into 4 rooms left atrium right atrium and right and left ventricle chamber.
  • Between the right and left separated by intertrioler septum (the wall between the foyer).
  • Between the right and left ventricular chambers separated by interventrikuler septum (the wall between the chambers)
  • Between the left atrium to the left ventricle is limited by the valve bikuspidalis (mitralis).
  • Between the right atrium and the left ventricle is limited by the valve trikuspidalis
  • Between the left ventricle to the aorta is limited by the valve semilunaris aortae.
  • The right chamber with limited pulmonary artery pulmonary valve semilunaris.

Chambers of the heart
Chambers of the heart is the heart that has the ability to pump blood, while the foyer as passive recipients of blood. Because of these functions, it is structurally muscle ventricles are thicker (stronger) than muscle porch.
Similarly, the right and left chambers muscle thickness is different because of different duties. left ventricle has a thicker muscle than muscles as it works right chamber pumps blood throughout the body, while the right chamber serves to pump blood to the lungs. However, the right chamber has a larger space than the left ventricle.


Heart valve
Functioning heart valves keep blood pressure and keep the blood does not flow back into place. Valvula mitralis and trikuspidalis open because of blood coming from a systemic vein (the superior vena cava and inferior vena cava) and the pulmonary vein, if the chambers to contract close, but valvula semilunaris open and vice versa. Valvula ends connected by chordae tendineae to the cubicle wall at papillary musculus (m = musculus. Muscles).
There are 4 valves in the heart. Namely mitral, tricuspid, aortic, and pulmonik (often also called pulmomer). The valve serves to regulate the blood flow in the right direction. Each valve has a cover called leaflets or cusps. Mitral valve leaflets have 2 pieces, others feature 3 leaflets. The right and left heart work together to create a pattern which continued constantly, causing blood to continue to flow to the heart, lungs and other body parts.


  • Blood enters the heart through two large veins (venous cava) inferior and superior oxygen carrying empty from the body into the right side of the porch.
  • When the porch contracts, blood flows from the right porch toward the right ventricle through the tricuspid valve.
  • When the chamber is full, the valve will close to triskupid prevents blood from flowing back into the atria when ventricular contraction.
  • When the chamber contracts, blood flows through the pulmonik valves into the arteries and lungs which in This part of the blood oxygenated.
  • Part pulmonary vein empties oxygen-rich blood containing oxygen from the lungs into the left porch
  • When the porch contracts, blood flows to part venrikel left through the mitral valve.
  • When venrikel full, the mitral valve is closed to prevents blood from returning to the porch when the ventricles contract.
  • When the ventricle contracts, blood leaves heart through the aortic valve into the entire collapse.

What a Heart and Position in Body

Posted by Unknown Tuesday, January 22, 2013 1 comments
What a Heart and Position in Body ~ Have you felt your heart rate pounding or beating strong and fast? Try to remember, When you're what? Why is that? Since the heart must continuously beat pumping blood fluid to flow to all parts of the body carry all substances that the body needs. When the body needs a supply of more substances, the heart beat faster.

 

Circulation system or kardivaskular system is a system composed of organs that function to move or distribute substances to and from cells. The system also helps the stability of temperature and acidity (pH) of the body (part of homeostasis)

Heart (English) aor cardia (greek) is a cone-shaped organs, muscular strength and it hollow, roughly the size of a human heart as big as fist hand men. Adult heart weight less than 300 grams, the heart is located in the chest cavity (vacuum thorac) position rather down and slightly to the left.  

The highlight of the heart (apex cordis) lying tilted to the left. Heart awake in place because the large blood vessels of heart that seemed to hang the heart on the chest.

What is coronary artery disease and its treatment

Posted by Unknown Monday, January 21, 2013 0 comments

What is coronary artery disease and its treatment ~ Coronary heart disease is one of the most feared murderers in the world. Usually, the disease is experienced by people berusian productive attacks and cause sudden death. 


A. The symptoms of coronary heart disease
  1. Chest pain and suppress 
  2. Prolonged headaches 
  3. Feeling his body on fire for no apparent reason 
  4. Complaint occurred around the sternum and neck 
  5. But most people who suffer from coronary heart disease do not experience any of the above symptoms. Suddenly, the patient's heart problems and chronic conditions.
B. The causes of coronaryThe disease is caused by narrowing and blockages in the coronary arteries. This is caused by the buildup of fatty substances (cholesterol, triglycerides) in the bottom wall of the artery (endothelium).

Once the oil accumulates, the blood flow will be blocked and can not affect the heart that heart in pumping blood. The perceived effect is the loss of oxygen and nutrients to the heart because the blood flow to the heart is reduced.

C. The factors that trigger heart disease:
  1. Smoking large amounts and over the years 
  2. Consuming foods high in fat or high cholesterol
  3. Hypertension who have suffered
