Definition - What does Vena Cava mean?
The vena cava is a large vein (a type of blood vessel) that transports deoxygenated blood (blood that the body has exhausted the oxygen supply from) back to the heart after it has moved through other parts of the body. There are two blood vessels called vena cava in the human body, these are the inferior and the superior. The inferior vena cava is sometimes called the posterior vena cava while the superior vena cava is sometimes called the anterior vena cava.

The vena cava is actually two veins, the inferior vena cava and the superior vena cava. The inferior vena cava transports blood from the part of the body below the waist and the superior vena cava transports blood from parts of the body above the waist.
