Description
The blood that enters the liver comes from two major sources, the hepatic portal vein and common hepatic artery.
Eighty percent of the blood that enters the liver travels through the hepatic portal vein. It delivers nutrient rich blood from the gastrointestinal tract to the liver; however, this blood is less oxygenated than the blood of the common hepatic artery.
Twenty percent of the blood that enters the liver travels through the hepatic artery proper and its distal branches.
