What is the name of the clear liquid secreted by the salivary glands in the mouth area?

The clear liquid secreted by the salivary glands in the mouth area is called saliva.

It is an essential component of oral health because it keeps the mouth moist, prevents dryness and discomfort, and aids in food digestion. 

Furthermore, saliva contains enzymes that help to break down carbohydrates and neutralize the acid produced by plaque, lowering the risk of tooth decay. 

The presence of food in the mouth stimulates saliva production, which causes saliva to be released from salivary glands.

Hence, the correct answer is saliva.
