The heart is a muscular organ in the human being, the blood works to pump through the blood vessels in the human blood. Pear shaped face down on the size of the equivalent of an adult 1.Cardiac function is crucial to the heart to keep the blood flowing and carries oxygen juice and food in every cell of body. The heart consists of several parties. Here are the parts of the human heart and its complete functions with heart anatomy pictures.Immediately we see the first:
The aorta is the largest artery in the body. It is in the upper part of the heart. aortic function is to carry oxygenated blood from the left ventricle to the body.
- Superior Vena lava
the superior vena cava (cava) is a large vein in the body. It is also at the forefront of the heart.A function of the superior vena cava is to highlight all the upper body to the heart, rich in carbon dioxide blood.
- pulmonary artery
pulmonary artery is transported from the heart into the pulmonary artery, the blood. The function of the pulmonary artery has been to replace the carbon dioxide and water vapor in the blood with oxygen.
- aortic valve
The aortic valve is located in the valve, which separates the left ventricle to the aorta. Changes in blood pressure on both sides of the valve causes the valve to be opened and closed. function of the aortic valve is to keep the blood flowing in the wrong direction.
Atrium is the majority of the atria, which corresponds to the veranda. There are two atrium left atrium (left atrium) and the right atrium (right atrium). Atrium upper two chambers of the four main chamber of the heart. The function of the left atrium receives blood is the lungs, which is rich in oxygen, and transport it into the left ventricle. Although the function of the right atrium receives blood from the body, which is rich in copy dioxide, then to offer the right ventricle.
- Pulmonary veins
pulmonary veins are veins that carry oxygen-rich blood against the lungs to the heart exactly into the left atrium. Reducing the size of the vena cava and pulmonary veins consists of the right and left pulmonary vein. The function of the pulmonary veins is to carry oxygenated blood to the heart, and then distributed throughout the body.
tricuspid or tricuspid valve is composed of a three valve leaflets. This valve can, when systolic contraction be opened and closed again. tricuspid valve function is separating the right atrium and right ventricle and to help drain deoxygenated blood from the right atrium to the right ventricle.
The mitral valve is bicuspid or the left atrium and the left ventricle.This valve into the left atrium via the left ventricle flowed in can open when the oxygen-rich blood separates. the function of the mitral valve is to prevent blood which is in the left ventricle back into the left atrium.
The ventricles are the two cavities of the four chambers on the underside of the core. Also called ventricular chambers. There are two types ventricle, the left ventricle (LV) and right ventricle (right ventricle). Ventricular function is to receive the blood from the atria and then the heart. left ventricular function is to receive the blood from the left atrium and to bring it to the whole body. right ventricular function is to receive blood from the right atrium and to bring it into the lungs.
- Vena Kava
The inferior vena cava or the inferior vena cava was the largest vein in the body. The function of the inferior vena cava is no blood from the lower body to the right atrium of the heart.
In addition to the parts of the image of the anatomy mentioned above, here are some other parts of the human heart:
- atrioventricular valve
atrioventricular or AV valves are located valves between the atria and ventricles. Atrioventricular valve function is to keep that blood can flow from the atria to the ventricles.
wall Heart 12
the heart wall is a part of the outer wall of the heart. heart wall consists of three layers, namely, endocardial (internal), myocardium (middle) and epicardial (outer). Endocardial consists of a flattened epithelial layer. Compound of infarction of the heart muscle (heart muscle) .Epicardium is a fibrous membrane. The function of the heart wall is to make the heart rate and prevent the heart that does not end.
