Answer:

Saliva is a mixture of water, mucus, antibacterial substance and digestive enzymes. Therefore, saliva has many uses. One of the digestive enzyme alpha-amylase helps to break down the starch present in our food in to simpler one like glucose and maltose. Whenever we chew, we activate these glands to secrete an enzyme to breakdown the food. Saliva has lubricating properties. It protect the inside cavity of our mouth, teeth and throats as we begin to swallow the food bolus. It also cleanses the mouth after the meal and dissolves it into chemicals that we perceive as taste.
