How does your throat keep germs away?

The throat plays a crucial role in the immune system by acting as a barrier to pathogens. It contains lymphoid tissues, such as the tonsils, which help trap and destroy germs. Additionally, mucus in the throat helps to trap foreign particles, while cilia (tiny hair-like structures) move these trapped germs toward the mouth, where they can be expelled or swallowed. Together, these mechanisms help prevent infections and keep the respiratory system healthy.
