Q:

Function of Bile juice?

Answer

Bile contains bile acids, which are critical for digestion and absorption of fats in the small intestine. Since bile increases the absorption of fats, it is an important part of the absorption of the fat-soluble substances, such as the vitamins A, D, E, and K. Besides its digestive function, many waste products, including bilirubin, a byproduct of red blood cells recycled by the liver are eliminated from the body by secretion into bile and elimination in feces.
