Random Fact #30
Veins push blood back to the heart by surrounding muscles contracting and moving the blood. The Great Saphenous Vein is surrounded by fat in your leg and can not use the leg muscles to move the blood. The vein therefore has a muscular wall that can contract to move the blood. This vein is not crucial and can be harvested and used in cardiac bypass surgery.
