The Gall blabber is a pear-shaped sac attached to the posterior surface of the liver by connective tissues. It has a fungus or expanded end, a body or main part and a neck which is continuous with the cystic duct, which unites with the hepatic duct from the liver to form the common bile duct.

In structure the gall bladder has the same layer of tissue as those of the alimentary canal with some modifications.

Functions

1. It acts as a reservoir of bile.

2. The lining membrane adds mucus to the bile.

3. It absorbs water which concentrates the bile.

4. By the contraction of the muscular walls bile is expelled from the gallbladder and passes via the bile ducts into the duodenuon.
