Answer 2

The small intestine is narrow in order to ensure that each and every particle of food ( chunk of food ) is absorbed into cells of the body. Moreover, the surface area of the inner walls of small intestine is far more than that of large intestine. The surface area is increased due to the presence of small projections called villi which are so characterized to especially absorb each chunk of food.

Some terms related to the chapter " Digestive System " : --
1. Villus ( plural Villi ) - The small projections formed in the inner walls of the small intestine.

2. Stomach - The phase in the digestive system where second step of digestion takes place. It secretes HCL.
