What secrets salivia?

Your salivary glands.

"The salivary glands secrete saliva into the mouth to assist in digesting foods. Humans have 3 pairs of major salivary glands: 1) parotid glands, 2) submandibular glands, and 3) sublingual glands. The parotid glands are the largest salivary glands and are located in front of the ear in the cheek area and slightly over the jaw line. The smaller submandibular glands are located under the jaw and the sublingual glands, the smallest major salivary glands, are located under the tongue. Hundreds of minor salivary glands, each about the size of a grain of sand, exist and line the mucous membranes inside the mouth." - See more at: (see related link)
