ANATOMY

Detailed explanation-1: -The extensive chemical process of digestion begins in the mouth. As food is chewed, saliva, produced by the salivary glands, mixes with the food. Saliva is a watery substance produced in the mouths of many animals. There are three major glands that secrete saliva: the parotid, the submandibular, and the sublingual.

Detailed explanation-2: -Animal digestion begins in the mouth, then moves through the pharynx, into the esophagus, and then into the stomach and small intestine.

Detailed explanation-3: -The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach.

Detailed explanation-4: -The digestive process begins in the mouth. Even before eating begins, the anticipation of eating stimulates glands in the mouth to produce saliva.

Detailed explanation-5: -A digestive enzyme in saliva called amylase (pronounced: AH-meh-lace) starts to break down some of the carbohydrates (starches and sugars) in the food even before it leaves the mouth.
