Granulocytic white blood cells (neutrophils), red blood cells and platelets, coloured scanning electron micrograph (SEM). Granulocytes are leukocytes with granules in their cytoplasm that contain destructive chemicals. Neutrophils are involved in inflammation and other immune responses. They assist in cellular defence (phagocytosis) of pathogenic microorganisms. Neutrophils travel from a capillary to infected regions where antibody-antigen complexes are located. A neutrophil destroys an antigen by engulfing it and injecting lethal chemicals. Macrophages will arrive later to consume any remaining debris. Neutrophils are involved in cellular defence (phagocytosis) of small pathogenic microorganisms. Magnification: x1,000 when shortest axis printed at 25 millimetres.
