The hepatic artery is a vital blood vessel that supplies oxygen-rich blood to the liver. It branches off from the celiac trunk, which is a major artery that provides blood to the upper abdominal organs. The hepatic artery plays a crucial role in maintaining the liver's health and function by delivering the necessary nutrients and oxygen. In addition to the hepatic artery, the liver also receives blood from the portal vein, which carries nutrient-rich blood from the intestines. This dual blood supply allows the liver to process nutrients and detoxify substances effectively, supporting overall metabolic functions in the body.
