Now, monocides ultimately differentiate into macrophages. And macrophages are the largest white blood cells of our body. They are very, very large phagocytic cells and these scavenger cells essentially move around our tissue and they seek out different types of harmful agents pathogens, bacterial cells and so forth. They engulfed them and then they essentially destroyed them. So monocides enter tissue and develop into macrophages which are large scavenger cells that engulf pathogens via phagocytosis. So the two type of phagocytitic cells, phagocytic cells inside our immune system are macrophages as well as neutrophils.
