Saliva is produced by all human individual, including all other animals. It contains water in much of its substance and somewhat frothy in nature. Produced in the mouth, saliva is formed by salivary glands present in our body. Digestion of our food is primarily dependent on mixing of saliva with our food in the mouth itself. Our body produces saliva when the food reaches inside the mouth and at the time when chewing process is taking place. Saliva serves as lubricants of the food. In that way saliva produced by salivary gland moistens the food and creates a bolus within mouth. This process makes the swallowing of the bolus very easy in order to reach to the stomach for second phase of digestion. Actually many people has misconception that digestion of food occurs in the stomach but it actually starts in the mouth and it is the primary process that makes digestion possible. Saliva also protects from desiccation to oral surfaces.
