Detailed explanation-1: -Mouth. 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. Saliva also has an enzyme that begins to break down starches in your food.

Detailed explanation-2: -The buccal cavity is the first cavity of the alimentary canal which includes teeth, tongue, and palate (Palate is the roof of the mouth. It separates the mouth and the nose.). The buccal cavity helps to take the food inside by the process of ingestion (ingestion is the process of taking food into the body).

Detailed explanation-3: -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-4: -The buccal cavity mainly comprises the primary organ of the digestive system including the teeth, tongue and salivary glands. The mouth is an opening through which the food is taken inside the body. It is bounded by lips and its inner parts comprise the cheeks, tongue, upper jaw and lower jaw.

Detailed explanation-5: -An enzyme called salivary amylase is found in the saliva of our mouth which breaks down large molecules of carbohydrates into smaller ones. These are easily and quickly absorbed by the intestine when they reach there. Thus, when we chew the food properly, it is digested well.
