Phagocytes of humans and other animals are called "professional" or "non-professional" depending on how effective they are at phagocytosis.The professional phagocytes include many types of white blood cells (such as neutrophils, monocytes,macrophages, and mast cells) and dendritic cells.The main difference between professional and non-professional phagocytes is that the professional phagocytes have molecules called receptors on their surfaces that can detect harmful objects, such as bacteria, that are not normally found in the body.Phagocytes are crucial in fighting infections, as well as in maintaining healthy tissues by removing dead and dying cells that have reached the end of their lifespan.
