The parotid gland is one of the largest salivary glands in the human body, located near the jaw and in front of the ears. Its primary function is to produce saliva, which helps in digestion and keeps the mouth moist. Saliva also contains enzymes that begin the process of breaking down food. In addition to aiding digestion, the parotid gland plays a role in oral health by helping to wash away food particles and bacteria. Problems with the parotid gland, such as infections or blockages, can lead to discomfort and swelling, highlighting its importance in maintaining overall health and well-being.
