Detailed explanation-1: -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-2: -The gastrointestinal tract consists of the oral cavity, pharynx, esophagus, stomach, small intestine, and large intestine. The accessory organs are the teeth, tongue, and glandular organs such as salivary glands, liver, gallbladder, and pancreas.
Detailed explanation-3: -Digestion begins in the mouth. 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.
