Wikipedia
The parotid gland is a major salivary gland in many animals. In humans, the two parotid glands are present on either side of the mouth and in front of both ears. They are the largest of the salivary glands. Each parotid is wrapped around the mandibular ramus, and secretes saliva through the parotid duct into the mouth, to facilitate mastication and swallowing and to begin the digestion of starches.
The word parotid (paraotic) literally means "beside the ear".
