What percentage of blood is supplied to the liver through the portal vein?

The hepatic portal vein supplies 75% of the blood to the liver, while the hepatic arteries supply the remaining 25%. Approximately half of the liver’s oxygen demand is met by the hepatic portal vein, and half is met by the hepatic arteries.

What percentage of cardiac output does the liver receive?

Does liver disease affect your heart?
