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.
Although, it is much longer than the large intestine, it has a much narrower diameter, thus accounting for its name. The majority of food digestion and nutrient absorption occurs in the small intestine. The small intestine receives partially digested food from your stomach.At the point when food reaches the duodenum of the small intestine, it has been mixed with stomach acid and manually broken up by the contraction of the stomach walls.ithin the microvilli of the small intestine are networks of capillaries and lymph vessels called lacteals. Capillaries are the smallest components of your blood vessels, the site at which your blood exchanges nutrients, oxygen and waste products with your bodyâs tissues.
