Overview of Blood Vessel Disorders of the Liver
The liver receives the oxygen and nutrients it needs in blood that comes from two large blood vessels:
Portal vein
Hepatic artery
The portal vein provides about two thirds of the blood. This blood contains oxygen and many nutrients brought to the liver from the intestines for processing. The hepatic artery provides the remaining one third of blood. This oxygen-rich blood comes from the heart and provides the liver with about half of its oxygen supply. Receiving blood from two blood vessels helps protect the liver: If one of these blood vessels is damaged, the liver can often continue to function because it receives oxygen and nutrients from the other blood supply.
