Detailed explanation-1: -Mechanical digestion in the oral cavity consists of grinding of food into smaller pieces by the teeth, a process called mastication. Chemical digestion in the mouth is minor but consists of salivary amylase (ptyalin, or alpha-amylase) and lingual lipase, both contained in the saliva.
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: -Mechanical digestion occurs from the mouth to stomach while chemical digestion occurs from the mouth to intestine.
Detailed explanation-4: -Food is initially broken down in the mouth by the grinding action of teeth (chewing or mastication) The tongue pushes the food towards the back of the throat, where it travels down the esophagus as a bolus. More items
