VENA CAVA

The vena cava is a large vein that runs along the right side of the body. It is divided into two portions, the superior vena cava and the inferior vena cava. The superior vena cava is the great vein that returns the blood from the head, arms and upper body to the right atrium of the heart. The inferior vena cava, which is larger than the superior vena cava, returns blood from the lower body and legs.
