Answer 1

Answer:

saliva is secreted from salivary glands

Answer 2

Explanation: 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. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

ROLE OF SALIVA: Saliva, the watery liquid produced by glands located under the tongue, is an essential component of the digestive process. Saliva is 98% water, so it moistens the mouth and helps compact food into softened particles for easier swallowing.
