ABSTRACT

In contrast to other organs in the body, the blood supply for the liver is twofold. Most blood (~75%+) reaching the liver is venous in origin, arriving via the portal vein and carrying nutrients from the GI tract and metabolic products and intermediates from throughout the body. Signicantly, as venous return, blood in the portal vein is deoxygenated. However, in addition to the venous ow,

a supply of oxygenated blood reaches the liver from the hepatic artery, a branch of the celiac trunk from the aorta.
