The gall bladder
The gall bladder is a small pouch that stores bile. Bile is a fluid that helps us digest food. It helps break down fats in food. Bile is made by the liver and stored in the gall bladder. The gall bladder is connected to the small intestine and the liver by the bile ducts.
The gall bladder and the bile ducts together are known as the biliary system. We have separate information about cancer of the bile duct.
