Detailed explanation-1: -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: -Ingestion – the taking in of food Food is taken into the mouth where it is physically broken down by the teeth into smaller pieces. The presence of food in the mouth triggers a nervous reflex that causes the salivary glands to deliver a watery fluid called saliva to the mouth.

Detailed explanation-3: -Mechanical digestion in the oral cavity consists of grinding of food into smaller pieces by the teeth, a process called mastication. Chemical digestion in the mouth is minor but consists of salivary amylase (ptyalin, or alpha-amylase) and lingual lipase, both contained in the saliva.

Detailed explanation-4: -The pharynx is where swallowing occurs. As food enters the pharynx, the tongue combines with the roof of the mouth (also called the soft palate) to push food back into the pharynx.
