Detailed explanation-1: -The food is ground up by the teeth and moistened with saliva to make it easy to swallow. Saliva also has a special chemical, called an enzyme, which starts breaking down carbohydrates into sugars.

Detailed explanation-2: -Mastication (chewing), in which food is crushed and mixed with saliva to form a bolus for swallowing, is a complex mechanism involving opening and closing of the jaw, secretion of saliva, and mixing of food with the tongue.

Detailed explanation-3: -Teeth tear and chop the food. Spit moistens it for easy swallowing. A digestive enzyme in saliva called amylase (AH-meh-lace) starts to break down some carbohydrates (starches and sugars) in the food. Muscles in the tongue and mouth work together to swallow the food and move it into the throat (pharynx).

Detailed explanation-4: -Saliva (you might call it spit) works with the teeth and helps make food soft and easy to swallow. It also has chemicals in it that start breaking down the food.
