# The Digestive Journey

Trace food through the mouth, oesophagus, stomach, small intestine and large intestine. Explain chewing, saliva, stomach mixing and nutrient absorption, then follow leftover waste into the rectum and out through the anus.

## Ready when they can

- Put the mouth, oesophagus, stomach, small intestine and large intestine in route order; explain that leftover waste enters the rectum and leaves through the anus
- Describe how teeth chew, saliva wets food and starts digestion, the oesophagus moves swallowed food, and the stomach churns and mixes food with digestive juices
- State that most nutrients are absorbed in the small intestine, while the large intestine absorbs water from leftovers and helps form more solid waste

## Lesson: The Digestive Journey

Food gives your body nutrients for energy and growth. Digestion breaks food down so your body can use it. Follow these main parts in order: mouth, oesophagus, stomach, small intestine and large intestine. Leftover waste then enters the rectum and leaves through an opening called the anus.

*(drawing: Follow the route from eating food to passing leftover waste out of the body.)*

Teeth chew food into smaller pieces. Saliva wets food and starts breaking down some of it. After you swallow, muscles push food down the oesophagus towards the stomach. The stomach churns food while mixing it with digestive juices, including acid. These actions help break food down into a thick mixture.

Food next reaches the small intestine, where digestion continues and most nutrients are absorbed through the walls. Blood carries absorbed nutrients around your body. Leftovers reach the large intestine, which absorbs water from them. The waste becomes more solid, enters the rectum and leaves through the anus.

**Recap.** Digestion starts in the mouth. Most nutrients are absorbed in the small intestine. The large intestine absorbs water from leftovers. Waste leaves through the anus.
