Detailed explanation-1: -Saliva as a whole (mixed) is the secretion of three pairs of large salivary glands (90% of total secretion) and numerous minor glands (up to 10%). The parotid glands produce enzyme-rich serous saliva, the submandibular glands produce mixed, mucin-rich saliva, and the sublingual glands produce mucous saliva.

Detailed explanation-2: -This process can start with the sight or smell of food. The liquid aids digestion, moistens your mouth, reduces infections in the mouth and throat, and helps protect your teeth and gums. You have 3 major pairs of salivary glands: Parotid glands, the largest, are on both sides of your face, in front of your ears.

Detailed explanation-3: -Saliva gland acinar cells are chloride and sodium secreting, and the isotonic fluid produced is rendered hypotonic by salivary gland duct cells as it flows to the mouth. The major proteins present in saliva are secreted by salivary glands, creating viscoelasticity and enabling the coating of oral surfaces with saliva.

Detailed explanation-4: -They are divided into two main types: the major salivary glands, which include the parotid, submandibular and sublingual glands, and the minor salivary glands, which line the mucosa of the upper aerodigestive tract and the overwhelming entirety of the mouth [1].
