Mouth

The mouth is the first part of the digestive system, where the process of digestion begins. It is responsible for the ingestion, mastication, and initial digestion of food. The mouth also plays a role in the chemical digestion of carbohydrates through the action of enzymes such as amylase.

Functions of the Mouth

1. Ingestion: The process of taking food into the mouth.
2. Mastication: Chewing and grinding of food to break it down into smaller pieces.
3. Salivary Secretion: The release of saliva, which contains enzymes that begin the digestion of carbohydrates.
4. Taste Sensation: The mouth contains taste buds that allow for the perception of different tastes - sweet, salty, sour, and bitter.
