Answer 1

Bile helps in emulsification of fats. i.e., breakdown of fats in smaller fat globules. Another role of bile is activation of lipase, enzyme required for digestion of fats. Bile helps break down fat and digest protein.

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, bile serves also as the route of excretion for bilirubin, a byproduct of red blood cells recycled by the liver.
