Function: Chemical digestion of food and absorption of nutrients into your blood. Longest section of your digestive tract. Your small intestine is around five metres long, making it the longest section of your digestive tract. Although it is longer than your large intestine it has a smaller diameter. This is why it's called the small intestine.
The intestine ends at the anus.. The function of the intestine is to digest and absorb food. After the initial stages of digestion (chewing and soaking in digestive juices in the stomach) the food enters the small intestine where it is mixed with other digestive chemicals including enzymes. The large molecules of which the food is made are broken down into small, soluble ones.
