What is the function of the vena cava?
Venae cavae are two main veins found in all vertebrates that breathe air. Like all veins, the function of vena cava is to transmit blood that has been deoxygenated from the body back to the heart. These veins are essential components of the circulatory system and each is responsible for returning blood from half of the body. Blood from the upper half passes a superior vena cava, while blood from the lower half passes the lower vena cava. Vena Cava can be seen from their inflow veins. The excellent vena Cava, which is located just above the heart, is made of intersection of left and right brachiocephalic veins. These veins return blood from the head, neck and arms, as well as from the upper spine and chest. Another vein, Azygos, collects blood from the wall of the chest and lungs and flows into the superior vena Cava, just above the heart.
The function of vena cava, which collects blood from the lower body, determines its different structure. LowerEna Cava begins near a small back, where the ilial veins are joined. Iliakal veins return blood that has been deoxygenated back from the feet. Many smaller tributaries are supplied to it when it runs near the spine, intersects the membrane and connects to the heart. These tributaries feed blood from genitalia, abdomen, kidney and liver.
Finally, the vena cava function is to ensure the correct operation of the circulatory system. By returning blood that was exhausted from her oxygen to the right atrium of the heart, the heart can then pump this blood into the lungs. In the lungs, blood receives oxygen that is vital to survival and returns it to the heart. The heart can then pump oxygenated blood all over the body. This vein important helps to return this blood for reuse after the body uses it.
To help with the function of vena cava, contractions from the heart of blood supply and supply pressure. There are no valves that separate Venae cavae from the right atrium. Instead, the heart contractions are transmitted by other veins and muscles. These contractions provide the pressure of the lack ofTo push deoxygenated blood into the heart. This process is essential to ensure continuous blood flow back to the heart.
