The document discusses allies of the immune system that help protect the body from pathogens. Keratin and mucus in areas like the skin and nasal passages act as physical barriers that trap and remove bacteria. Cilia in the nasal cavity help move mucus and trapped pathogens out of the body. Beneficial bacteria in the skin and gut also compete with harmful bacteria. White blood cells, lymph nodes, vaccines, and vitamins further aid the immune system in identifying and fighting pathogens.
