The Digestive system

The food we eat has to be broken down into other substances that our bodies can use. This is called digestion.

Without digestion, we could not absorb food into our bodies and use it.

Digestion happens in the digestive system. This is a series of organs that break the food down so it can be absorbed into our bloodstream.
