"귀밑샘" refers to the parotid gland, which is one of the major salivary glands located near the jaw and in front of the ears. It plays a crucial role in producing saliva, which aids in digestion and helps keep the mouth moist. The gland is responsible for secreting enzymes that begin the process of breaking down food. In addition to its digestive functions, the parotid gland can be affected by various conditions, such as infections or tumors. Symptoms of issues with the gland may include swelling, pain, or difficulty swallowing. Regular check-ups can help monitor its health and function.
