Question

If we say "digestion begins in the mouth " how would you explain this

Answer 1

Digestion begins in the mouth means that when we take food, it is not in the form to be digested. so firstly it's required to break it into small manageable pieces with the help of teeth. that's why food is mixed with saliva and converted into small pieces to be swallowed.

Answer 2

Answer:

Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells. Chemical digestion begins in the mouth when food mixes with saliva. Saliva contains an enzyme (amylase) that begins the breakdown of carbohydrates.
