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 made up of the duodenum, jejunum and ileum. It is covered by mesentery. Duodenum. The duodenum connects the stomach to the small intestine. Most digestive enzymes enter the small intestine in the duodenum. Jejunum. The jejunum is the middle part of the small intestine, between the duodenum and ileum. Most digestion and nutrient absorption takes place in the jejunum. Ileum. The ileum is the last and longest part of the small intestine.
