What do tonsils help fight the body against?

Tonsils play a role in the immune system by helping to defend the body against infections, particularly those caused by bacteria and viruses that enter through the mouth and throat. They contain immune cells that produce antibodies and help trap pathogens, preventing them from spreading further into the body. By doing so, tonsils contribute to the body's first line of defense, especially during early childhood when the immune system is still developing.
