Question

what is the role of saliva in digestion food

Answer 1

Saliva enables the food bolus to travel down the oesophagus easily due to its lubricating function. It also contains the protein amylase which helps to break down starch during digestion.

Answer 2

Answer:

The digestive functions of salivainclude 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. Thus, digestion of food occurs within the mouth, even before foodreaches the stomach.
