Meaning and Definition
A type of large white blood cell that is part of the innate immune system.
In immunology and hematology, a mononuclear phagocytic leukocyte produced in the bone marrow, which circulates in the bloodstream before migrating into tissues to differentiate into macrophages or dendritic cells. It plays a crucial role in engulfing pathogens and presenting antigens to other immune cells.
