Functions of the small intestine. The small intestine is the part of the intestines where 90% of the digestion and absorption of food occurs, the other 10% taking place in the stomach and large intestine. The main function of the small intestine is absorption of nutrients and minerals from food. Digestion involves two distinct parts.
The small intestine is 5â6m in length, and most of the chemical digestion occurs within the first metre. Once digested into smaller molecules, absorption can take place.Millions of tiny finger-like structures called villi project inwards from the lining of the small intestine.These structures greatly increase the surface area of contact that the products of digestion have with the small intestine, allowing for their rapid absorption into the bloodstream.illions of tiny finger-like structures called villi project inwards from the lining of the small intestine.
