monocytes

Large white cells

Monocytes are large white blood cells that circulate in the bloodstream before migrating into tissues, where they develop into macrophages or dendritic cells.

They're part of the immune system's first line of defense, engulfing pathogens and dead cells.

A monocyte count appears in standard blood tests: Her monocytes were elevated, suggesting infection.
