- Small Intestine. The small intestine is a winding, tightly folded tube about 20 ft (6 m) long in adults. It connects to the stomach on the top end and to the large intestine (colon) on the bottom end. Most of the food a person consumes is digested and absorbed in the small intestine. The lining of the small intestine has tiny, finger-shaped tissues (villi).

Small Intestine: Function, Length & Problems The duodenum breaks down the food. The jejunum and the ileum absorb nutrients and send them into the bloodstream, according to the Cleveland Clinic. The inner lining of the small intestine is folded back and forth to increase surface area for better nutrient absorption. These folds create microscopic finger-like projections that are called villi.

Function of the Small Intestine (Digestive System) It is the part of the digestive tract where approx 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.That is, absorption of the nutrients and minerals in the food ingested, usually via the mouth, at an earlier stage in the digestive process. Sodium ions (Na +) move from the lumen of the small intestine into epithelial cells by diffusion and active transport. 2  They are then actively transported into blood capillaries on the other side of the epithelial cells. 3  Chloride (Cl -) can passively follow Na + ions into epithelial cells, or be actively transported.
