What is the role of saliva in the digestion of food?  



Saliva is a watery liquid secreted by the salivary glands present in the mouth and it is responsible for digestion of starch in our food.


  • Saliva lubricates and moistens food , thus aiding in swallowing.  
  • An enzyme called amylase helps to breakdown starch into a simpler sugar called maltose to be easily absorbed by the body. 
  • Since amylase is present in the saliva, it is called salivary amylase .
