The liver lies on the right side of the abdominal cavity beneath the diaphragm. Blood is carried to the liver via two large vessels called the hepatic artery and the portal vein. The heptic artery carries oxygen-rich blood from the aorta (a major vessel in the heart).
The liver is located in the upper right hand area of the abdomen, just beside the stomach and below the right lung. The liver is the largest gland in the body. It weighs about 1500 grams and is surrounded by a thin membrane called Glisson's capsule.
