Inferior Vena Cava

The inferior vena cava is a large-caliber blood vessel which collects deoxygenated blood from the legs and abdomen and carries it to the heart. It arises at the junction of the common iliac veins, runs up vertically and parallel to the abdominal aorta, and goes through the diaphragm, ending up at the right atrium of the heart, where the returning blood is pumped to the lungs by the right ventricle. Along its vertical course, the inferior vena cava is fed by the gonadal, renal, suprarenal, and hepatic veins.
