PATHOLOGY

Detailed explanation-1: -These are largest of the salivary glands, secreting saliva to facilitate mastication and swallowing, and amylase to begin the digestion of starches.

Detailed explanation-2: -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-3: -Serous secretion is a more liquid opalescent fluid composed of water and proteins, such as the digestive enzyme amylase. Depending on the types of cells present, the glands may be specific, giving off only one of these two substances; or they may be mixed, giving off combinations of both secretions.
