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 main purpose of the small intestine is to digest and absorb food into the body. The small bowel is divided into three parts: the duodenum (which food from the stomach empties into), the jejunum and the ileum (which empties undigested food into the large intestine or colon).
