With the help of teeth, physical digestion of food takes place which helps the food to cut into small pieces, chews and grind it. Further salivary glands present in the mouth helps in the chemical digestion of food with the help of enzymes. It contains enzymes known as salivary amylase which digest the starch present in food into sugar. We can say that the digestion of carbohydrate or starch begins in the mouth itself.

The contraction and expansion of the movement of the walls of the food pipe after entering the slightly digested food is known as peristaltic movement.
