The gall bladder is a small pear-shaped organ. It is situated on the right side just below liver.

Liver produces about 1-1.5 litre bile, a yellow colored fluid every day. The bile duct is a tube that carries bile from the liver to the small intestine. About 50 ml is stored in gall bladder.. When a patient eats a fatty meal, the gall bladder squeezes out the bile to help absorb the fats.
