What is saliva mainly composed of?

Explanation:
Water is the main component because saliva is an aqueous secretion—the majority of its volume is just water. This watery nature provides the solvent environment in which all other components exist and function. The water allows saliva to lubricate the mouth, dilute and buffer acids, transport enzymes like amylase, and carry minerals such as calcium and phosphate that aid remineralization. Electrolytes and various organic molecules are present, but in far smaller amounts than water, so they play supporting roles within the watery medium.
