ANATOMY

Detailed explanation-1: -Salivary glands contain three major cell types: acinar cells, ductal cells, and myoepithelial cells. Despite their different locations, each of these glands shares the same fundamental structure, branched ducts that open into the oral cavity and glandular secretory end pieces, called acini, that produce saliva.

Detailed explanation-2: -Submandibular and sublingual glands are mixed. In general, acinar (secretory) cells are responsible for the production of the primary saliva. The ductal cells are responsible for further modifications of saliva until it is secreted in the mouth.

Detailed explanation-3: -Saliva is Made Of Mostly Water If you’re wondering what saliva is made of, it’s 99% water. This is no surprise considering the body is made of 60% water. The remaining 1% of saliva contains digestive enzymes, uric acid, electrolytes, mucus-forming proteins, and cholesterol.
