Do You Know How Saliva is Produced & Delivered to Our Mouth ?

1) Saliva is produced by three pairs of major salivary glands: the parotid, submandibular, and sublingual glands, as well as numerous minor salivary glands located throughout the mouth and throat.


2) The process of producing and secreting saliva is regulated by the autonomic nervous system, which controls involuntary bodily functions. 


3)When food is sensed in the mouth or when the brain signals the need for saliva, the autonomic nervous system triggers the salivary glands to produce and secrete saliva.


4)Saliva is produced by the acinar cells in the salivary glands, which filter and modify the fluid that is initially secreted.

5)The acinar cells filter out large molecules and modify the composition of the fluid to include enzymes, electrolytes, and other substances.


6)The modified fluid is then transported through a series of ducts that converge to form the main duct, which empties into the mouth.


7)As the saliva travels through the ducts, more water is reabsorbed, which concentrates the fluid and makes it more viscous.


8)Finally, the saliva is secreted into the mouth through the salivary ducts, where it helps to moisten and lubricate the mouth, aid in digestion, and protect the teeth and oral tissues.


9)Saliva production and secretion is a continuous process, with an average adult producing between 0.5 and 1.5 liters of saliva per day.
