Each part of our body needs to be recharged with energy, and we get that energy from food.
We could try and put the food straight into the parts of our body where it is needed鈥

Because we have a digestive system!
鈥 series of organs that break food down in a useful way for the body.
And it gets rid of all the body's waste as well!

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.
