C
The liver receives one-third of the total cardiac output from two major sources: the hepatic artery, which provides oxygenated blood, and the portal vein, which is supplied with nutrient-rich blood from the gut, pancreas, spleen, and stomach. The portal vein, which accounts for 75% of the total liver blood flow, branches into sinusoids to transport blood to each lobule. Intralobular veins empty into larger veins and then into the hepatic vein, which empties on the posterior surface of the liver and eventually into the vena cava. The hepatic artery also divides and subdivides between the lobules, supplying sinusoids with oxygenated blood before emptying into the hepatic vein.
