Answer 1

The process of digestion of food in humans begins in mouth.

Explanation: 

The process of digestion begins the moment food enters your mouth. Your teeth physically break down the food into smaller pieces by chewing (mechanical digestion), while your salivary glands simultaneously release saliva. Saliva contains an enzyme called salivary amylase, which immediately starts the chemical digestion of complex carbohydrates (starches) into simpler sugars before the food even reaches your stomach.
