Monocyte
Monocytes are a type of white blood cell that play a key role in the immune system. They are produced in the bone marrow and circulate in the bloodstream, where they help defend the body against infections. When they encounter harmful germs, monocytes can move into tissues and transform into macrophages or dendritic cells, which actively engulf and destroy pathogens, and assist in triggering other immune responses. Monocytes are essential for detecting threats, cleaning up cellular debris, and coordinating the body's defense mechanisms to maintain health.
