Explain the role of mouth in digestion of food.

AcademicBiologyNCERTClass 10

The mouth is the entry point of food during ingestion. Inside the mouth, chewing breaks the food into small pieces and saliva mixes with food that can be easily passed through to the stomach through the esophagus.

In the mouth, the saliva contains salivary amylase which helps in the breakdown of starch. An enzyme in saliva helps to break down starch into maltose sugar. The enzyme Lysozyme present in the food kills the bacteria in our mouth.

There are four types of teeth: Canine, Incisors, Molars, and Premolars, which help in chewing the food.
