S3.3.2 For the adult
Digestion
What happens to food after I swallow it?
What this chapter teaches
Food is broken into tiny pieces as it moves through the gut. Only very small pieces can pass through the wall of the small intestine into the blood. What is left goes on to the large intestine, and leaves the body as waste.
Three questions to ask
There is no one right wording. Listen for the idea.
- Where does food go after you swallow it, step by step?
- Why do we chew food well?
- What would happen to a piece of food that was never broken down?
After the chapter, the learner can
- Trace food through the mouth, gullet, stomach and intestines
- Explain why food must be broken into small pieces to be absorbed
What they copy into their notebook
Food goes mouth, gullet, stomach, small intestine, large intestine. It is broken into tiny pieces. Only tiny pieces pass through the gut wall into the blood.
