Answer: Saliva initiates digestion by moistening food, breaking it down with enzymes like amylase.

Here are the functions of saliva in the digestion of food:

1. Moistens Food: Facilitates easier chewing and swallowing.
2. Digests Starches: Contains alpha-amylase to start breaking down starches into simpler sugars by breaking α 1-4 glycosidic bonds.
3. Enhances Taste: Acts as a solvent for taste substances.
4. Forms Food Bolus: Helps in the formation of a cohesive bolus for swallowing.
5. Protects Oral Tissues: Lubricates and buffers to protect against decay and erosion.
6. Antimicrobial Properties: Controls bacterial growth, maintaining oral hygiene.
7. Supports Oral Health: Contributes to the overall health of the mouth and teeth.
