2. The Production of Saliva

Three major salivary glands are primarily responsible for the production of saliva, though a few minor glands are involved as well. The submandibular glans produces around 65% of the saliva in the human mouth, the parotid produces about 20%, and the sublingual creates between five and seven percent. These glands are controlled by the autonomic nervous system, which is part of the nervous system and responsible for supplying smooth glands and muscles.
