The Large Intestine's Role in the Digestive System

The final stage of digesting food involves the large intestine.

Water reabsorbed

Water is reabsorbed into the body in the large intestine.

Passing of faeces

Any food that cannot be digested and absorbed remains in the large intestine.
Food that cannot be digested passes along the large intestine.
- Undigested food comes out of the anus as faeces.
