- 1Fore gut fermenters (ruminants)These animals have four part stomachs to break down their diet of grass - to be able to access the cellulose. The digestion starts in the Rumen, then the Reticulum and then the food is chewed again. Finally the food is passed back into the Omasum and finally to the abomasum (also known as the true stomach as it contains similar enzymes to a human stomach)
- 2Hind-gut FermentersContains a very large Caecum where bacteria assists in the break down of cellulose
- 3OesophagousA long muscular tube connecting the mouth and the stomach. The cite of peristalsis
- 4PeristalsisThe contracting of muscles in the oesophagous causing the food to be pushed downwards into the stomach.
- 5The MouthWhere food first enters the body. Mechanical digestion takes place, using the teeth, with the help of Salivary Amalayse to break down the food
- 6Mechanical DigestionThe physical break down of foods into smaller parts through grinding, crushing, cutting, mushing etc
- 7Chemical DigestionThe breakdown of food with the use of chemicals to break the food into even smaller parts. Takes place after mechanical digestion.
