Question

explain the role of mouth in digestion of food

Answer 1

The mouth is the beginning of the digestive tract; and, in fact, digestion starts here when taking the first bite of food. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.

Answer 2

First food enters in mouth or buccal cavity. In buccal cavity salivary glands secrets saliva which breaks food into simple sugar and then food is passed to stomach through oesophagus.
