sa·li·va

(să-lī'vă),
A clear, tasteless, odorless, slightly acidic (pH 6.8) viscid fluid, consisting of the secretion from the parotid, sublingual, and submandibular salivary glands and the mucous glands of the oral cavity; its function is to keep the mucous membrane of the mouth moist, to lubricate food during mastication, and, in a measure, to convert starch into maltose, the latter action being effected by a diastatic enzyme, ptyalin.

saliva

Spit The clear, semifluid secretion of the major and minor salivary glands, and mucus-secreting cells of the oral cavity; saliva keeps the oral cavity moist, lubricates food during mastication–which facilitates deglutition, and, via its enzyme content-alpha amylase, begins the process of digestion. See Salivary glands, Sputum.

saliva

A slightly alkaline, watery fluid secreted into the mouth by the SALIVARY GLANDS. Saliva contains the digestive enzyme amylase capable of breaking down starch to simpler sugars. Saliva keeps the mouth moist, dissolves taste particles in food so that they can stimulate the taste buds on the tongue and lubricates food during mastication to assist in swallowing.

saliva

a viscous, transparent liquid containing water, salts, MUCIN and (sometimes) salivary AMYLASE. Saliva is secreted by cells of the salivary glands which, in humans, occur in three pairs, one in the cheek and two between the bones of the lower jaw. The quantity of saliva produced depends on the type of food being consumed. Dry foods and acidic foods stimulate a copious volume of nonviscous saliva, while liquids such as milk stimulate small quantities of thick saliva.
