Chewing mechanically breaks down food into smaller particles, increasing its surface area for enzymatic action. This process also mixes the food thoroughly with saliva, ensuring the even distribution of digestive enzymes and promoting effective digestion.

Chewing, or mastication, aids in the digestion process through several mechanisms. Firstly, it mechanically breaks down food into smaller particles, increasing its surface area for enzymatic action. This enhances the efficiency of digestive enzymes, such as amylase in saliva, in breaking down complex carbohydrates. Additionally, chewing initiates the release of saliva, which contains enzymes and lubricates food for easier swallowing. The thorough mixing of food with saliva facilitates the formation of a semiliquid mixture known as bolus, which can be easily transported through the digestive tract. Overall, chewing is a critical initial step in the digestive process, optimizing the subsequent breakdown and absorption of nutrients.
