Common hepatic artery
The common hepatic artery is a branch of the celiac artery that supplies oxygenated blood to the liver, pylorus, pancreas, and duodenum. It runs on the right inside the lesser sac and enters the lesser omentum where it then passes upward toward the porta hepatis. Giving off the right gastric artery, it then splits into the proper hepatic artery and the gastroduodenal artery. The proper hepatic artery continues on into the porta hapatis where it splits into the left and right hepatic arteries that supply the liver. The right hepatic artery supplies the gallbladder by giving off the cystic artery. The gastroduodenal branch of the common hepatic artery passes behind the duodenum and divides into the right gastroepiploic artery and the superior pancreaticoduodenal artery. The right gastroepiploic artery runs along the curve of the stomach and connects with the left gastroepiploic artery. The pancreaticoduodenal artery then divides into anterior and posterior branches that circle the head of the pancreas and connect with the inferior pancreaticoduodenal artery.
