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: -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.

Detailed explanation-3: -Digestion ends in the small intestine of the human body. The digestive process starts in the mouth and finishes in the small intestine; the large intestines’ primary role is to absorb any residual water from undigested food and here the undigested food is fermented by the bacteria.

Detailed explanation-4: -Figure 2: The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation.
