In humans, between 0.5 and 1.5 litres of saliva are produced every day. The secretion of saliva (salivation) is mediated by parasympathetic stimulation; acetylcholine is the active neurotransmitter and binds to muscarinic receptors in the glands, leading to increased salivation.
Secretion of saliva is under control of the autonomic nervous system, which controls both the volume and type of saliva secreted. This is actually fairly interesting: a dog fed dry dog food produces saliva that is predominantly serous, while dogs on a meat diet secrete saliva with much more mucus. Paralytic Secretion: Claude Bernard observed that after section of the chorda tympanic nerve in a dog or cat, a scanty secretion of thin turbid saliva is produced which increases until the seventh or eighth day, at which it reaches a peak level, and diminishes about the third week. He called it as paralytic secretion. An adult person produces from 0.5 to 2 litres of saliva per day, but only 2–10% of the fluid is produced at night.

The secretion produced is mainly mucous in nature; however, it is categorized as a mixed gland. Unlike the other two major glands, the ductal system of the sublingual glands does not have intercalated ducts and usually does not have striated ducts either, so saliva Soy isoflavone aglycones were administered at 25 mg per day to 15 subjects with an average age of 67.9 ± 8.0 years for 2 months, and salivary secretion was analyzed. 2010-08-26 performance on RSST and saliva secretion, because the secretion of saliva changes and decreases slightly with increasing age combined with medication [23].

This is secreted at a rate of approximately 0.5 milliliters per minute. During eating or any other situation that triggers maximal salivation, the salivary flow can increase up to 20-fold. PROPERTIES OF SALIVA i) VOLUME:- 1000 to 1500 ml of saliva is secreted per day and , it is approximately about 1ml/minute . Contribution by each major salivary gland is 32. On average, a healthy person produces between 0.75 and 1.5 liters of saliva each day. Saliva production peaks when a person is eating and is at its lowest during sleep. The physiological secretion generates 0.75–1.5 L per day, with a decrease during the night [2].
