Macrophages are derived from which type of immune cell?

Macrophages are derived from monocytes, which are a type of white blood cell. When monocytes leave the bloodstream and migrate into tissues, they differentiate into macrophages. This differentiation allows them to take on specialized roles in the immune system, including the phagocytosis of pathogens, debris, and dead cells, as well as the activation of other immune cells. Macrophages play a critical role in both innate and adaptive immunity, making them essential for a well-functioning immune response. Understanding this origin is crucial as it highlights the pathway through which these powerful immune cells are formed and their importance in the body’s defense mechanisms.
