Hepatic artery

Hepatic Artery

The Hepatic Artery (pronounced: hɪˈpatɪk ˈɑːrtəri) is a blood vessel that supplies oxygenated blood to the liver, gallbladder, stomach, and duodenum. The term "hepatic" is derived from the Greek word "hepar" meaning liver, and "artery" is derived from the Latin word "arteria" meaning windpipe, as the ancients believed arteries were air-filled, rather than blood-filled.

Anatomy

The hepatic artery is a branch of the celiac artery. It typically divides into the proper hepatic artery and the gastroduodenal artery. The proper hepatic artery further divides into the left and right hepatic arteries to supply the corresponding lobes of the liver.

Function

The hepatic artery provides about 25% of the blood supply to the liver, with the remainder coming from the portal vein. The blood from the hepatic artery is oxygen-rich, which is vital for liver function.

Clinical Significance

Damage to the hepatic artery can lead to serious complications, including liver failure. It is also a key area of focus in liver transplant surgeries.
