The descending vena cava is made up by the confluence of the right and 

 left brachio-cephalic or innominate veins ; and the vena azygos major, tin- pen- 

 cardiac, thymic, and cesophageal veins are its subsequent tributaries. It returns 

 the blood to the right auricle of the heart from above the diaphragm.
