part of the abdomen on the right side beneath (and loosely attached to) the diaphragm. It is reddish brown in colour and weighs about 1.5 to 2 kg. A remarkable feature of the liver is that it receives a double supply of blood : (a) fresh arterial blood from the hepatic artery arising from the aorta, and (b) from the portal vein carrying the finished products of digestion from the intestine. Both these large bloodvessels branch repeatedly into a network of thousands of tiny capillaries making the liver a highly vascular organ.
Blood from both the blood vessels mixes in the liver through its kupffer cells. Blood from liver carrying the nutrients reaches the vena cava through the hepatic vein. Thus nutrients processed by the liver reach the bloodcirculation through vena cava.
