Inferior vena cava Structure [edit]. The inferior vena cava is formed by the joining of the left and right common iliac veins and brings collected blood into the right atrium of the heart. It also joins with the azygos vein (which runs on the right side of the vertebral column) and venous plexuses next to the spinal cord.n the embryo, the inferior vena cava and right atrium are separated by the valve of the inferior vena cava, also known as the Eustachian valve.

Cardiopulmonary Syndromes (PDQÂ®)âPatient Version The superior vena cava returns blood from the upper body to the heart, and the inferior vena cava returns the blood from the lower part of the body. The superior vena cava is thin-walled, and the blood is under low pressure. It lies near lymph nodes in the chest. Therefore, when the lymph nodes or the aorta of the heart get bigger, the superior vena cava is squeezed, blood flow slows, and complete blockage may occur.
