What is the function of the vena cava and aorta?
The left side of the heart receives oxygenated blood from the pulmonary vein and pumps it into the aorta, while the right side of the heart receives deoxygenated blood from the vena cava and pumps it into the pulmonary vein. The pulmonary vein and aorta also have valves connecting them to their respective ventricle.
What is the function of vena cava Class 10?
Function. The inferior vena cava is a vein. It carries deoxygenated blood from the lower half of the body to the right atrium of the heart. The corresponding vein that carries deoxygenated blood from the upper half of the body is the superior vena cava.
What is the function of anterior and posterior vena cava?
function. …of two major trunks, the anterior and posterior venae cavae, that deliver oxygen-depleted blood to the right side of the heart. The anterior vena cava, also known as the precava, drains the head end of the body, while the posterior vena cava, or postcava, drains the tail, or rear, end.…
What are veins?
Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation. Arteries and veins are two of the body’s main type of blood vessels. These vessels are channels that distribute blood to the body.
Which is bigger aorta or vena cava?
Arteries and veins are blood vessels which deliver oxygenated and deoxygenated blood from and to the heart respectively.

The inferior vena cava is ultimately responsible for the transport of almost all venous blood (deoxygenated) from the abdomen and lower extremities back to the right side of the heart for oxygenation.
Where is the biggest vein in your body?
What is the function of the Vana Cava?
Vana cava is the vein that carries deoxygenated blood collected from your body into the right atrium of your heart. The superior vena cava brings in deoxygenated blood from the upper part of the body (head, neck, arms; organs above the diaphragm).
How does the vena cava carry blood to the heart?
First, vena cava collects blood from veins, then returns to the right atrium of the heart. The vena cava has a large diameter, but its walls are very thin because of low pressure exerted by venous blood. The inferior vena cava carries blood from the lower part of the body.
What is the function of the IVC and superior vena cava?
The primary function of the IVC is to carry deoxygenated blood that has circulated through the lower half of the body back to the right atrium of the heart. The IVC is responsible for moving all of the blood below the diaphragm, while the superior vena cava handles the blood above the diaphragm.
Which is a congenital condition of the superior vena cava?
There are a few common congenital conditions of the superior vena cava including: 8 1 Persistent left superior vena cava (persistent LSVC): is a common anomaly of the systemic veins.

Why is blood darker in the inferior vena cava?
The inferior vena cava is also referred to as the posterior vena cava. The inferior vena cava is a large vein that carries de-oxygenated blood from the lower body to the heart. De-oxygenated blood means most of the oxygen has been removed by tissues, and therefore the blood is darker.
