When elementary school, you may have been taught about human organs, one heart. Simply put the heart is divided into four parts, the chamber (ventricle) left, right ventricle, porch (atrium) left and right atrium. The heart is the organ that serves as a blood pump, well pump blood throughout the body (large blood circulation) and pump blood to the lungs (small circulation). More on parts of the heart, it turns out to have heart valve (separator) in parts. According to the medical dictionary is a specialized tissue heart valve that is located in the heart of the duties set the sequence of blood flow from one section to another. To find more detailed description about the valves, see the following explanation:

  • The tricuspid valve is the valve that separates the right atrium (right atrium) and vartikel right (the right ventricle) and consists of 3 leaves the valve, the tricuspid valve opens to drain the blood contains less oxygen which has collected in the right atrium (right atrium) to ventikel right (the right ventricle) to be pumped to the lungs. If ventikel contraction (systole) the tricuspid valve will close to prevent blood that is in vartikel right (the right ventricle) Artrium back to the right (the right atrium) .Meanwhile, the pulmonary valve (pulmonary valve) is open to drain blood into the pulmonary artery (pulmonary artery).
  • Valve pulmonary valve (the valve pulmonary) is the valve that separates the ventikel right (the right ventricle) to the pulmonary artery (pulmonary artery), these valves open to allow blood poor in oxygen from the right ventricle can get into the pulmonary artery, and after dilairkan valve this closes so that blood does not come back to the heart.
  • The mitral valve (bicuspid) is a valve that separates the left Artrium (left atrium) with ventikel left (left chamber). This valve opens when the oxygen-rich blood is collected into the left atrium flowed into the left ventricle, and will close when the left ventricle of the contract, so this valve serves to prevent oxygen-rich blood in the left ventricle of coming back into the left atrium, the blood can be pumped out through the aortic valve into the aorta.
  • The aortic valve is the valve that separates the left vartikel (left chamber) with the aorta. This valve opens when the left ventricle of oxygen-rich blood flow throughout the body, and will close after the blood was drained so that blood does not return to the heart.

So that admins can tell, may be useful to you, if there is criticism, suggestion, and disclaimers please attach it in the comments field.
