Lingual Tonsil: What It Is & Its Role in Immunity

Lingual Tonsil

That little bump at the back of your tongue is called the lingual tonsil. All tonsils are part of your lymphatic system, which is a network of vessels and nodes that help fight off infections. Your lingual tonsil is located at the base of your tongue near your throat and helps trap germs that enter your mouth before they can cause an infection.
