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 a long and narrow tube about 6 to 7 meters (20 to 23 feet) long. Food completes its chemical decomposition in which a compound is split into other compounds by reacting with water in the small intestine with the help of the liver, pancreas, and intestinal glands who pour their secretions into it.
