Food swallowed --- passes along alimentary canal (tube running from mouth to anus)

The processes involved  are:

1. Ingestion; taking food in

2. Digestion; the break down of food into small, soluble molecules

3. Absorption; in to the bloodstream for distribution

4. Assimilation; the use of absorbed food materials in the cell

5. Egestion; removal of undigested food as faeces
