This is the dominant blood supply to the liver parenchyma and allows the liver to perform its gut related functions such as detoxification.

The portal vein which is rich in nutrients and relatively high in oxygen provides two thirds of blood flow to the liver. The vascular anatomy of the liver is complex.
