Liver produces bile – a chocolate green colored liquid containing bile salt, fat liquid, cholesterol and other chemical materials.

This emulsion kept in the gall-bladder until it is required to digest fats in your small intestine. When eating, your gall bladder would contract and releases bile through sistic duct and enter ordinary bile duct.

This bile duct then will bring the bile to the top small intestine (duodenum) where there it will first break fats in your food.
