Answer» Answer: Hope this helps. Please follow me and Mark as Brainliest. :) 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 is mixed. In serous secretions, the main type of protein secreted is alpha-amylase, an enzyme that breaks down starch into maltose and glucose, whereas in mucous secretions the main protein secreted is mucin, which acts as a lubricant. 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. |
