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.
Bilirubin is produced during the recycling of red blood cells in the liver. Bile also serves as a carrier for cholesterol to be excreted.
