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 primary role of the large intestine is reabsorption of water from stool. It also absorbs some nutrients not taken up efficiently by the small intestine, and houses most of the symbiotic bacteria in your gut.   The large intestine does not digest food. It simply is used to absorb water and compact the stool. The majority of digestion occurs in the small intestine where nu â¦ trients are also absorbed for the body.
