Produce Saliva is the term used to describe the process of salivation, which is the production of saliva in the mouth. Saliva is a clear liquid that is secreted by glands in the mouth and helps to lubricate food for easier swallowing and digestion. It also contains enzymes that help to break down food and protect the teeth from decay. Salivation is an important part of the digestive process and is triggered by the sight, smell, or taste of food.
