Bile is a sticky, yellow-green digestive fluid made by the liver. Its main job is to break down fats into fatty acids so that they can be absorbed by your body through the digestive tract. Bile is stored in the gallbladder and is sometimes also called gall. Bile also gets rid of certain waste products from your body, such as hemoglobin, a protein that comes from destroyed red blood cells and excess cholesterol.
