Bile is a thick digestive fluid secreted by the liver and stored in the gallbladder. It facilitates digestion by breaking down fats into fatty acids, which can be absorbed by the digestive tract. Bile contains mostly cholesterol, bile acids (also called bile salts), and bilirubin (a breakdown product of hemoglobin). Bile also contains very small amounts of excreted copper and other metals.
