Monocyte

Monocytes circulate in the bloodstream searching for microbes or dead cells to clean up. Once in contact with intruders or debris, they transform into dendritic cells or macrophages, which are like vacuum cleaners that devour invaders and protect other cells from harm.

NEWS FLASH: Monocytes are large immune cells that have a kidney-shaped nucleus.
