Macrophage and platelets. Coloured scanning electron micrograph (SEM) of platelets (green) attached to a macrophage white blood cell (turquoise). Platelets,or thrombocytes,are fragments of white blood cells. When blood clots,red blood cells (erythrocytes) are trapped within a fibrin protein mesh (beige),which is formed in response to chemicals secreted by the platelets. Macrophages phagocytose (engulf) and destroy pathogens,dead cells and cellular debris. Magnification: x7000 when printed at 10 centimetres wide | |
