What type of cell is a macrophage?

Macrophages are a type of phagocytic white blood cell, which means they are part of the immune system responsible for identifying and engulfing pathogens such as bacteria and viruses. They play a crucial role in the body's defense mechanism by not only digesting these harmful invaders but also by presenting pieces of them (antigens) to other immune cells, enhancing the adaptive immune response. This function makes them essential for maintaining health and fighting infections. Therefore, identifying macrophages accurately as phagocytic white blood cells aligns with their vital role in immunity.
