Final answer:

The skin, macrophages, and natural killer cells are important nonspecific defense mechanisms against pathogens.


Explanation:

skin is a nonspecific defense against pathogens. It serves as a physical barrier that prevents pathogens from entering the body and causing infection.

Macrophages are immune system cells that can both phagocytize pathogens and produce chemicals promoting inflammation, making them versatile defenders against infections.

Natural killer cells work alongside cytotoxic T cells to combat virally infected cells, offering an additional layer of defense in the immune response.
