ANATOMY

Detailed explanation-1: -Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb. Saliva also contains an enzyme called lingual lipase, which breaks down fats.

Detailed explanation-2: -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-3: -Saliva is 98% water, so it moistens the mouth and helps compact food into softened particles for easier swallowing. Our teeth and tongue work as a food processor, using saliva as the liquid necessary to create a mixture suitable for the stomach.

Detailed explanation-4: -The muscular tongue helps mix the food with saliva and the enzymes it contains. When you swallow, the lump of chewed food, now called a bolus, passes into the pharynx. The pharynx connects the mouth to the rest of the digestive tract.

Detailed explanation-5: -Salivary amylase is a glucose-polymer cleavage enzyme that is produced by the salivary glands.
