Functions of Liver
The various functions of Liver are carried out by the liver cells or hepatocytes. The
liver is thought to be responsible for up to 500 separate functions. Currently no

Features: The liver is large and solid gland situated in the right upper quadrant of the
abdominal cavity. In the living subject , the liver is reddish brown in colour, soft in
consistency , and very friable. It weights about 1600 g in males and about 1300 g in
females.
External Features: The liver is wedged shaped. It resembles a four sided pyramid
laid on one side.
Histology: Liver is covered by Glisson' s capsule. There are hexagonal lobules with
portal radicles at 3-5 corners. Each radicle contains bile ductule, branch each of
portal vein and hepatic artery. Central vein lies in the centre and all around the
Central vein are the hepatocytes in form of laminae. On one side of the lamina is the
sinusoid and on the other side is a bile canaliculus.
Portal lobule seen in human is triangular in shape with three central veins at them sides and the portal tract in the centre.
The liver acinus is defined as the liver parenchyma around a preterminal branch of
hepatic arteriole between two adjacent central veins. The liver acinus is the
functional unit of liver. Blood reaches the acinus via branches of portal vein and
hepatic artery to open into the sinusoids to reach the central vein. On the other
hand, the flow of bile is along bile canaliculi, bile ductules and the Interlboluar bile
ducts.
