- Describe the functions of the organs of the digestive system in relation to:
- Ingestion – the taking of substances, e.g. food and drink, into the body.
- Digestion – the breakdown of food (physical digestion and chemical digestion).
- Absorption – the movement of nutrients from the intestines into the blood.
- Assimilation – uptake and use of nutrients by cells.
- Egestion – the removal of undigested food from the body as faeces.
