The part of the mouth that secretes enzymes that help prepare the food for digestion in the stomach is the salivary glands. The major salivary glands are the parotid, submandibular, and sublingual glands. They all secrete saliva into the mouth, the parotid secretes through tubes that drain saliva, the sublingual through many ducts in the floor of the mouth and the submandibular under the tongue.
