One of the body's largest solid organs, the adult liver weighs about three pounds. It is located near the stomach, in the upper portion of the abdomen under the rib cage, and is divided into two sections called lobes. The liver is connected to the small intestine by the bile duct.
Bile, produced in the liver, flows through the bile duct to the gallbladder, where it is first stored, and then released into the small intestine after you eat, to help your body digest and absorb fats.
The liver receives blood from two sources: the hepatic artery and the portal vein. The portal vein carries nutrients from the stomach and the intestine to the liver. The hepatic artery carries oxygen from the heart and lungs to the liver. There are also three hepatic veins that return blood from the liver to the heart.
