The daily volume secretion of saliva typically ranges from 1000 to 2000 ml. Saliva production is a continuous process and plays several essential roles in digestion, oral health, and maintaining the moisture of the oral cavity. Salivary glands secrete saliva in response to a range of stimuli, including the anticipation of food, the taste or smell of food, and even physical stimulation of the mucous membranes in the mouth.

Saliva contains various components, including enzymes, electrolytes, and antimicrobial agents, each contributing to its function. The average daily production aligns well with the physiological needs of the human body to aid in digestion, lubrication, and oral hygiene without exceeding the physiological limits of saliva secretion. In healthy adults, variations can occur based on hydration, diet, and other factors, but the standard range remains between 1000 and 2000 ml per day.
