Step-by-step explanation:
The white blood cells that comprise 3-7% of circulating white blood cells (WBCs), are phagocytic, and can migrate out into body tissues to differentiate into macrophages are called "Monocytes." Monocytes are a type of white blood cell known for their phagocytic abilities and their role in the immune response. When they migrate into tissues and mature, they become macrophages, which are essential for engulfing and digesting pathogens, dead cells, and other debris in the body's defense against infections and maintaining tissue health.
