Answer 1

Villi are small finger-like projections found inside the inner walls of the small intestine. They v increase the surface area for absorption of the digested food. ... The surface of the villi absorbs the digested food materials.

Bile is a fluid that is made and released by the liver and stored in the gallbladder. Bile helps with digestion. It breaks down fats into fatty acids, which can be taken into the body by the digestive tract.

The cellulose of the food is digested here by the action of certain bacteria which are not present in humans.

Glucose is a simple sugar which can be readily absorbed by the body. Once inside, glucose undergoes oxidation, which results in the release of ATP, a high-energy molecule that provides energy for the cell
