medicalschool:

Blood flow from the body (aka the systemic circuit) returns to the heart via two large vessels known as the superior and inferior vena cavas. In some cases, a patient is born with an absent inferior vena cava; which is a problem if you want all the deoxygenated blood from your lower half to return to the heart. When this happens, the azygous vein, one of the veins that drains into the superior vena cava, can be used instead. This vein will be much larger than normal due to the need for increased blood flow. Instead of draining into the inferior vena cava, blood vessels in the lower half of the body drain into the enlarged azygous vein.

Supercomputer Simulated Heart

Alya Red, a project of the Barcelona Supercomputing Center that tries to understand the wondrous organ that is the heart and when the mechanism fails. The simulator generates electrical signals to try and exactly mimic the speed at which the signals propagate across the heart. An attempt to create an accurate electro-mechanical model of a heartbeat all with the help of 10,000 processors.
