 Large and Small Circulation

The heart and cardiovascular system of veins, hence, in need of blood-borne oxygen and nutrients to the body responsible for ulaştırmakla.

Right side of the heart in the right atrium (atria), the right ventricle (ventricle), pulmonary artery and superior vena cava and inferior vena cava is formed. This section is a small circulation (pulmonary circulation or pulmonary circulation) provides (in the figure are shown in blue). Left side of the heart of the pulmonary veins (2 right, 2 left side, a total of 4 units), left atrium, left ventricle and the aorta occurs. This is part of a large circulation (systemic circulation) is responsible (as shown in red).
Possible to talk about two kinds of circulation in the body:
Small circulation:Of the blood by way of the lungs provides the oxygenation of. The right side of the heart is dedicated to this work. Organs of oxygen used by the impoverished blood (dirty blood! Fact is not dirty, only oxygen is fair, for some reason are used in such a false statement!) Javanese inferior vena cava and superior vena Javanese is called the right atrium via a large vein. Here passes through the tricuspid valve and right ventricle. Right ventricular contraction in this blood from the pulmonary artery (pulmonary artery) arteries and veins with the oxygenation of the blood in the lungs is provided.
Large circulationOxygen-rich blood from the lungs become the largest circulation for the use of organs by the body system. The left side of the heart is responsible for this work. Oxygen-enriched blood (fresh blood! This also was named the wrong reason!) Pulmonary veins returned to the lung (pulmonary veins), and from there via the left atrium into the left ventricle through the mitral valve income. With this blood vessel from the aorta in the left ventricle to the body sends to him. Aorta, the artery from the heart of the largest. After leaving the heart, including aortic heart to various organs and branches are oxygenated dokularımıza feeding and giving the parties shall continue until the lower abdomen.
Circulating in the blood of the heart in this way is possible with the contraction of the heart in a certain order. Blood in the ventricles before contraction empties the atriums, the aorta and pulmonary artery, and then sends the blood in the ventricles are contracting. Of the heart within a certain order with the schedule in this manner is an excellent contraction of the of the heart is possible with the transmission system.
Continuous forward flow of blood in the heart and heart valves is possible: the ventricles of blood between the atrium and ventricles atriumlara elope with covers (mitral and tricuspid valves), blood in the ventricles with the aorta and pulmonary arteries, the ventricles elope back covers of the vessels (the aortic valve and pulmonary valve ) becomes (See: HEART ANATOMY / Heart valves).
