The proper hepatic artery is also called the hepatic artery proper. It comes from the common hepatic artery and then runs beside the portal vein and the common bile duct; together, these make up the portal triad. The proper hepatic artery branches off into a small supraduodenal artery down to the duodenal bulb. At that point, the right gastric artery branches away from the proper hepatic artery, and goes toward the left, to run along the lesser curvature of the stomach. There, it meets the left gastric artery, one branch of the celiac trunk.
