Human saliva is a complex, aqueous solution primarily composed of water, electrolytes, mucus, enzymes, and antimicrobial agents. It plays a crucial role in digestion, oral health, and maintaining the balance of oral microbiota. The pH of saliva usually ranges from 6.2 to 7.6, making it slightly acidic to neutral, which helps in breaking down food and protecting teeth from decay. Additionally, the enzymes in saliva, such as amylase, begin the digestion of carbohydrates.
