The hepatic portal system is the system of veins comprising the hepatic portal vein and its tributaries. The liver consumes about 20% of total body oxygen when at rest, so the total liver blood flow is quite high. Blood flow to the liver is unique in that it receives both oxygenated and partially deoxygenated blood.
