A human liver normally weighs 1.44--1.66 kg (3.2--3.7 lb), and has a width of about 15 cm . It is both the heaviest internal organ and the largest gland in the human body . Located in the right upper quadrant of the abdominal cavity, it rests just below the diaphragm, to the right of the stomach and overlies the gallbladder . </P> <P> The liver is connected to two large blood vessels: the hepatic artery and the portal vein .
