The salivary glands in mammals are exocrine glands that produce saliva through a system of ducts. Humans have three paired major salivary glands (parotid, submandibular, and sublingual) as well as hundreds of minor salivary glands.[1] Salivary glands can be classified as serous, mucous or seromucous (mixed).

In serous secretions, the main type of protein secreted is alpha-amylase, an enzyme that breaks down starch into maltose and glucose,[2] whereas in mucous secretions the main protein secreted is mucin, which acts as a lubricant.[1]

In humans, between 0.5 and 1.5 litres of saliva are produced every day.[3] 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.[3][4]
