The Hepatic Portal Vein is one of the most unusual blood vessels in the body. It carries blood from the capillaries of almost the whole digestive system to the liver where it goes through another set of capillaries before returning to the heart. In addition, it is the only vein that does not have valves. Given these characteristics describe and explain the structure of the vessel as it pertains to vascular resistance.
