What Are White Blood Cells?
Reviewed: Dr. Gromatzky
6. Monocytes
Monocytes make up around 5 - 12% of the white blood cells in our system. They are made in our bone marrow and will live for several days. They patrol the body until they find pathogens, at which point they turn into a macrophage. The macrophage will then destroy the pathogen by engulfing and destroying it.
Monocytes also perform another very important function, which is to help keep the body clean. When cells in our body die, they need to be removed and monocytes are largely responsible for this. Monocytes are also very important because they help with the healing and repair of our bodies.
