Description : What is saliva? State its role in the digestion of food -Biology

Last Answer : Saliva is a watery fluid secreted by the salivary glands in the mouth. The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin.

The saliva pH is approximately 6.8. It is thus a slightly acid pH. Saliva lubricates the food bolus and initiates the enzymatic extracellular digestion of food. It also works as a buffer for the mouth pH and it has an important role of having IgA antibodies (also present in tears, colostrum, mother’s milk and in the mucosae of the intestine and airways) that protect the organism against pathogens.
