Salivary glands are a group of glands located in the mouth and throat that produce saliva, which plays a crucial role in digestion and oral health. Saliva contains enzymes that help break down food, lubricate the mouth and throat, and protect against bacteria and viruses. Dysfunction of the salivary glands can lead to dry mouth, difficulty chewing and swallowing, and an increased risk of dental problems. Research in this area explores the anatomy, physiology, and disorders of the salivary glands, as well as potential treatments and therapies to improve their function.
