Proper hepatic artery

The hepatic artery proper (also proper hepatic artery) is the artery that supplies the liver and gallbladder. It raises from the common hepatic artery, a branch of the celiac artery. The HAP accounts for 10% of hepatic blood flow and 30% of its oxygen supply, with the rest provided by the portal vein; this double blood supply makes the liver far more resilient to vascular disease than other major organs.
