The liver The liver is your largest internal organ. About the size of a football, it's located mainly in the upper right portion of your abdomen — beneath the diaphragm and above your stomach — but a small portion extends into the upper left quadrant.
Why is the liver so important?Because of the importance of the liver and its functions, evolution has ensured that it can regrow rapidly as long as it is kept healthy. All vertebrates, from fish to humans, have the ability to regrow the liver. The liver is the only visceral organ that can regenerate.
What is the blood supply to the liver?The liver is divided into two lobes and has a rich blood supply obtained from two sources; 1) the portal vein delivers blood from the gastrointestinal tract (stomach, intestine, colon) and spleen, and 2) the hepatic artery supplies blood from the heart.
What is the weight of the liver?The liver is one of the most versatile and important organs. Weighing between 3.17 and 3.66 pounds (lb), or between 1.44 and 1.66 kilograms (kg), the liver is reddish-brown with a rubbery texture. It is situated above and to the left of the stomach and below the lungs. The skin is the only organ heavier and larger than the liver.
