Question

Why is saliva necessary for the sense of taste?

Answer 1

Chemicals from the food dissolve in saliva and are then sensed by the taste buds.

Explanation:

In order for the sense of taste to function, chemicals from the food that is being chewed must dissolve in the saliva with which it is mixed. These dissolved chemicals are then sensed by the various taste buds on the tongue to give us the sense of taste.
