What happens in your intestines?

Learn about the different roles the intestines play in the digestive system.


The intestines are divided into two parts: the small intestine and the large intestine.

1. Small intestine

Digested food is absorbed in the small intestine. This means that it passes through the wall of the small intestine and into the bloodstream. The blood then carries the useful substances around the body to where they are needed.

2. Large intestine

By the time the contents reach the large intestine, most of the digested food has been absorbed. This just leaves waste material that the body doesn’t need or can’t digest. This is called faeces or poo, which we get rid of when we go to the toilet.

Partially digested food arrives in the intestine from the stomach.
