1 Bile contains bile acids, which are critical for digestion and absorption of fats and fat-soluble vitamins in the small intestine. 2  Many waste products, including bilirubin, are eliminated from the body by secretion into bile and elimination in feces.
Bile, which is made in the liver and needed to digest fat, is secreted into the beginning of the small intestine. It is then reabsorbed at the end of the small intestine (the ileum) and taken back to the liver where it is used again. This circuit is called enterohepatic circulation.
