The saliva The buffering system of the oral cavity. Saliva is secreted by various kinds of salivary glands located at different parts of the oral cavity. In humans, the total volume of saliva secreted daily is approximately 750 ml. The pH of saliva ranges from 6.7 to about 7.4. The tongue is not all that.
