The intestine is a long tube that is split into the small and large intestine, through which food travels from the stomach and out of the body while it is being digested.

Nutrients are important substances that living things use to stay alive and healthy. Animals take in nutrients from their food.

The rectum is the end part of the large intestine that holds faeces before it leaves the body through the anus.

Animals make solid waste in the form of faeces.

The anus is the hole at the end of the digestive system through which solid waste is pushed out.
