Study Notes
Saliva Composition
- Saliva is produced by three major salivary glands: sublingual, submandibular, and parotid glands, and minor glands: buccal, palatine, and lingual glands
- Major glands account for 93% of saliva production, and minor glands for 7%
Saliva Function
- Saliva acts as a defense system for oral tissues
- Saliva also plays a role in taste perception
Physical Characteristics of Saliva

- The term "symbionts" originates from the Greek words "syn" meaning "together" and "bios" meaning "life"
Acinar System
