The Mouth

The Mouth is the first portion of the alimentary canal that receives food and begins digestion by mechanically breaking up the solid food particles into smaller pieces and mixing them with saliva. The oral mucosa is the mucous membrane epithelium lining the inside of the mouth.


Mouth:
1. Mechanical digestion – making food into small pieces  easier digest
2. Saliva – chemical digestions  carbohydrates  sugar
Amylase  rice and bread
Slimes, food  slide down the esophagus
