What is "saliva"?
Saliva is a watery fluid produced by the salivary glands in the mouth that helps in the initial stages of digestion by moistening food, facilitating swallowing, and initiating the breakdown of carbohydrates through the action of enzymes like amylase. It also helps in maintaining oral health by washing away food particles and bacteria, and it plays a role in speech and taste perception.
