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: -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-3: -Saliva moistens the mouth for comfort, lubricates as you chew and swallow, and neutralizes harmful acids. It also kills germs and prevents bad breath, defends against tooth decay and gum disease, protects enamel, and speeds up wound healing.
Detailed explanation-4: -Chemical digestion begins in your mouth with your saliva. The process continues in your stomach and is completed in your small intestine. The majority of chemical digestion takes place in your small intestine.
Detailed explanation-5: -Saliva lubricates and moistens food, thus aiding in swallowing. An enzyme called amylase helps to breakdown starch into a simpler sugar called maltose to be easily absorbed by the body.
