Blood clot, coloured scanning electron micrograph (SEM). Red blood cells (erythrocytes) are trapped within a fibrin protein mesh (light pink). The fibrin mesh is formed in response to chemicals secreted by platelets (bright pink), fragments of white blood cells. Clots are formed in response to cardiovascular disease or injuries to blood vessels.
