- Remind pupils about the way in which the body uses food,
eg for energy,
for growth, and ask them how the products of digestion reach other parts of the body. Use secondary sources,
eg video clips, ICT simulations, to show how simple molecules,
eg glucose molecules, are transported to cells,
eg in the muscles.
- Ask pupils which of the food types they hadn't considered during the work on the products of digestion. Establish that fibre and undigested food is passed through the gut and egested in faeces.

- state that the blood transports products of digestion to every cell in the body
- use models to describe how smaller molecules are transported in the blood
- state that some food material cannot be digested and is passed out of the body as faeces
