Functions of Small Intestine
Complete Digestion of Food
The partially digested food is absorbed by the duodenum of the small intestine along with the digestive juices from the liver, pancreas and its own walls. The liver secretes the bile juice, which converts fat into tiny droplets so that their digestion becomes easy. The pancreas produces pancreatic juice that breaks down fats into fatty acids and glycerol. The intestinal juice secreted by the walls of the small intestine breaks down starch and carbohydrates into simple sugars. These sugars are known as glucose. It also converts the proteins into amino acids. All these simple, broken down forms are called the digested food.
