The villi are numerous small folds found on the intestinal wall.  Their function is to increase the surface area of the small  intestine to ensure the quick absorption of nu â¦ trients.
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.
