1. The food that we take is of complex nature.
2. It is converted into simpler molecules with the help of biological catalysts called as enzymes. Enzyme salivary amylase breaks down starch into a simple sugar maltose.
3. In the mouth, the food is crushed and wetted with saliva secreted by the salivary glands so the food can smoothly pass through the soft lining of the alimentary canal.
4. Thus digestion of food starts in the mouth itself.
