a Lebelled Diagram of the Heart : Anatomy and physiology Heart

Heart is the organ system in the main kardiovaskuler. Heart was established by a muscular organs, and the Apex cordis base, left and right atrium and right and left ventrikel. Heart size is approximately 12 cm long, 8-9 cm wide thick seta approximately 6 cm.
Heavy heart about 7-15 oz or 200 to 425 grams and a little more than the fist. Every day the heart rattle and 100,000 times in the period of the heart pumping 2000 gallons of blood, equivalent to 7571 liters of blood.
The position was located the heart of both tuberculosis and chest are in the middle, on the diaphragma thoracis and located approximately 5 cm above processus xiphoideus.
On the right edge is located at the cranial edge cranialis pars cartilaginis Costa dextra III, 1 cm lateral edge of the sternum. On the right edge is located at the caudal edge cranialis pars VI cartilaginis Costa dextra, 1 cm lateral edge of the sternum
The left edge are the heart of the cranial edge caudal pars II cartilaginis Costa Sinistra sternum in the lateral edge, the edge is on the left caudal space intercostalis 5, approximately 9 cm in the left linea medioclavicularis.

Membrane that envelop the heart called the pericardium which consists of fibrosa layer and serosa, in the cavum pericardii containing 50 cc that functions as a lubricant so that there is no friction between the pericardium and epicardium. Epicardium is the outermost layer of the heart, the next layer is the layer miokardium where this layer is the layer thick. Last layer is a layer of endocardium.
There are 4 rooms in the heart where two of the space is called the atrium and the rest is ventrikel. At the cloud known as the atrium and foyer with closet ventrikel known.

Between the right atrium and ventrikel kana tone valve that separates the two is ktup tricuspid, whereas in the left atrium and left ventrikel also have a valve called the mitral valve. Second valve is functioning as a barrier that can be opened and closed at the time of blood from the atrium entrance to ventrikel.

1. Right Coronary
2. Left Anterior Descending
3. Left Circumflex
4. Superior Vena Cava
5. Inferior Vena Cava
6. Aorta
7. Pulmonary artery
8. Pulmonary vein
9. Right Atrium
10. Right Ventricle
11. Left Atrium
12. Left Ventricle
13. Papillary Muscles
14. Chordae Tendineae
15. Tricuspid Valve
16. Mitral Valve
17. ValveFungsi main pulmonary heart is pumping darh to the entire body where at the time of the heart muscle-pumping heart muscle (miokardium) that move. In addition, heart muscle also has the ability to cause electrical stimulus.
Second is the atrium space with a thin wall of muscle because of the low pressure caused by the atrium. Instead ventrikel have a thick wall of muscle, especially ventrikel that have left three more layers of thick ventrikel right.
Activities contraction heart pumping blood to the body overlooks always started by the electrical activity. Electrical activity started in nodus sinoatrial (SA nodus), which is located in the cleft between the vena Cava suiperior and right atrium. Nodus SA on the waves so depolarisasi spontaneously evoke action potential spread through the muscle cells atrium, nodus atrioventrikuler (nodus AV), the His, Purkinje fiber, and finally to the whole muscle ventrikel.

Therefore, the heart does not have to do the rest for the contraction to meet the needs of the body, the heart requires more blood than other organs. The flow of blood to the heart from the coronary arterial-right and left. Both coronary arterial out of the aorta is approximately ½ inch above aorta valve and running on the surface of the pericardium. Then arteriol and a fork in the capillary walls ventrikel. Occurred after the exchange of O2 and CO2 in the capillary, the flow of ventrikel taken from the vena through vena coronary and straight into the right atrium where the flow of blood from the vena whole body will be empty.
Ditubuh circulation of blood circulation there are 2 that tuberculosis and systemic circulation. Circulation tuberculosis ventrikel right from the start to the arterial pulmonalis, large and small arterial, capillary go to tuberculosis, after a paru's exit through a small vena, vena pulmonalis and finally back to the left atrium. Circulation has low pressure that is approximately 15-20 mmHg in the arterial pulmonalis.
Systemic circulation starting from the aorta to the left ventrikel ago major arterial, minor arterial, arteriole and to the entire body and to venule, a small vena, vena large, inferior vena Cava, superior vena Cava eventually return to the right atrium.



Systemic circulation has a special function as a source of pressure that tinggindan carry oxygen to the network that need. In the capillary terjadin exchange O2 and CO2 on the systemic circulation of O2 and CO2 go out in the capillary circulation in tuberculosis O2 entry and exit from the capillary CO2.
Volume of each component in the blood circulation is different. 84% of the volume of blood in the body found in the systemic circulation, where 64% in vena, 13% in the arterial and 7% in arteriol and capillary.

Labeled Diagram of Fiber functions for Heart Health

Want to keep the heart remain healthy? From now on you change eating patterns. Avoid fatty food and lots of fibrous food consumption is high.

Heart is the organ of the most vital for human beings. Heart healthy will produce the quality of life better. However, not everyone has the heart condition that functions perfectly. Patterns of living that is not healthy can trigger various types of diseases. Heart disease that is found most often coronary heart, the chest pain (angina), heart and rheumatism.

Heart disease coronary heart disease is the most penderitanya. This disease attacks the blood vessel and can cause a heart attack. Heart attack due to the arterial duct clog so prevent oxygen distribution and nutrition to the heart. However, not all heart disease caused by a blood vessel.

There is also a disruption such as abnormal heart rhythms (heart rattle is not normal). The heart of the rattle too slow (below 60 times per minute) is called bradyarrhythmias. Meanwhile, a rattle above 100 per minute with a tachyarrhytmias. All interference is in the heart usually caused by aberration and is usually congenital birth.

Similarly with heart failure or heart failure, known as heart disease is the most frightening. Not mean that the heart can not work at all. However, the heart does not rattle, as appropriate. There is also a disturbance such as heart valve heart disease (heart valve damage) which is a congenital aberration.

Although many species, however, especially heart disease due to stoppage of blood vessel can be avoided or overcome with mengonsumsi foods contain fiber, particularly the type of fiber called betaglukan. In fact, various studies prove, fibrous foods, especially the type of fiber is able to reduce the degree betaglukan bad cholesterol (low densy lipoprotein / LDL) in blood. If the LDL level in blood is low, health heart became more assured.

"Fiber betaglukan itself can be found in processed grain products are known as oat or havermout. Oat Fiber as a charming grin binding fat in the blood and remove them through the dirt," said a specialist in clinical nutrition from the Central Pertamina Hospital (RSPP) Dr Kusuma fatma RD .

Not until there are, the research conducted in the United States found that wheat or oat fiber is soluble fiber that can lower LDL cholesterol (bad cholesterol) cholesterol without lowering HDL (good cholesterol). "Fiber also contains oat glikemi low. As such, cereal is very good for diabetics because the level of blood sugar produced after eating a very low," he said again.

High LDL level is the main cause of increased cases of coronary heart. Although there are therapy farmakologi faster to lower LDL, with wheat cereals consume more healthy and without side effects. However, it takes a while.

According to nutrition experts berkacamata thick, the cereal is a good source of nutrition because it contains vitamin E, zinc, selenium, copper, iron, and magnesium. Cereal can be a good source of protein for the body.

To get the maximum results, every day someone should consume 70 grams of oat. The amount must be right because if excessive, the result will not be maximum. One thing that is not less important when the decrease in blood cholesterol level is a sport regularly.

Especially the bad cholesterol, answerable as a cause of coronary heart because it causes blood vessel stopped and harden (aterosklerosis). As a result, the blood does not flow smoothly or clog. If the clog is the flow of blood to the heart, the coronary heart disease occur (PJK). If the leads to the brain, the stroke occurred. Can also prevent the circulation of blood in the legs, giving rise to the color black.

The coronary heart disease should receive due attention to this still was ranked as the first human murderer. Based on the data of the world health body (WHO) in 2001.

Each year approximately 7.2 million deaths due to coronary heart. The process of blood vessel stoppage the sooner this happens when people apply the pattern of life does not often eat healthy food such as fast food, soft drink or drinking sweet drinks too often and does not offset with a white water sports and rare.

Other sources of fiber, in addition to the wheat can also be found in avocado, grape, apple, berry and citrus fruit. Avocado has a womb glutation antioxidants and saturated fat not only useful to neutralize free radicals and the fat that is harmful in the body. In the wine there is a flavonoid, such as catechin and quercentin functions to facilitate the flow of blood, prevent the oxidation reaction to bad cholesterol, and reduce the formation of plaque on blood vessel. "Vitamin C in wine can also neutralize free radicals," he said again.

While the apples are in a lot of pectin, the type of fiber is a useful measure to help reduce blood cholesterol. Pectin binding of cholesterol comes from food. For example, from milk, meat, and eggs, and in order to remain in the intestine.
