The submandibular glands are two small salivary glands located beneath the jaw, or mandible. They play a crucial role in producing saliva, which helps with digestion and keeps the mouth moist. Saliva contains enzymes that begin breaking down food and also helps protect the teeth from decay. These glands are part of the body's salivary system, which includes other glands like the parotid glands and sublingual glands. When we eat, the submandibular glands release saliva to aid in swallowing and tasting food. Proper function of these glands is essential for oral health and overall digestion.
