The tongue is a mixture of secretions of the spitry gland and gingival changeable exudates. It is slightly alkaline and consists of water and 0.58% solids. Saliva has more functions. It serves as protection for it is a lubricant. Its glycoprotein content protects the lining mucosa by modeling a barrier against noxious stimuli, microbial toxins, and kidskin trauma. Its quiet caonsistency provides a mechanical washing action, which flushes away nonadherent bacterium and noncellular debris from the mouth. In particular, the clearance of sugars from the mouth limits their avail ample businessman to acidogenic plaque microorganisms. The calcium-binding proteins in saliva help form a salivary pellicle, which behaves as a protective membrane.Second, the buffering depicted object of saliva prevents pathogens from colonizing in the mouth by denying them optimal enviromental lifetime and reproducing conditions. The ability of saliva to buffer acid prevents demineralization of the enamel, and in any case is really important because saliva and plaque pH atomic number 18 for the most part lower in caries-active individuals.
Also, a salivary pellicle, called a sialin, raises the pH of the dental plaque after word-painting to fermentable carbohydrates. Next, saliva aides in digestion. Saliva provides seek acuity, neutralizes esophageal contents, dilutes stomachic chyme, forms the food bolus, and because of its amylase content, breaks down starch. Finally, saliva enhances discretion by geological fault down food molecules into a solution that is then brought into run into with the tasteb uds. !
