The parotid gland is one of the major salivary glands located near the jaw, specifically in front of the ears. It produces saliva, which helps in the digestion of food and keeps the mouth moist. The gland is responsible for secreting a watery type of saliva that contains enzymes, aiding in the breakdown of carbohydrates. In addition to its digestive functions, the parotid gland plays a role in oral health by helping to wash away food particles and bacteria. It is connected to the mouth through the Stensen's duct, which opens near the upper second molar tooth. Conditions affecting the parotid gland can lead to swelling or infections, such as mumps.
