唾腺
The function of the salivary glands is to secrete saliva, which has a lubricating function, which protects the oral mucosa of the mouth during eating and speaking. Saliva also contains digestive enzymes (e.g. salivary amylase) and has antimicrobial action and acts as a buffer. Salivary gland dysfunction occurs when salivary rates are reduced and this can result in xerostomia (dry mouth).
