Macrophages are derived from neutrophils. lymphocytes. monocytes. basophils. eosinophils.

Macrophages are actually derived from monocytes, which are a type of white blood cell. When monocytes migrate from the bloodstream into tissues, they can differentiate into macrophages, where they play a critical role in the immune system by engulfing and digesting pathogens, dead cells, and cellular debris. This transition allows them to become powerful defenders against infections! In the world of immunology, macrophages are often described as the "clean-up crew" of the immune system. They not only help swallow up invaders but also play a part in activating other immune cells and communicating with them to coordinate an effective response. So, next time you think of these cells, imagine them donning their superhero capes in the battle against germs!
