Blood clot. Coloured scanning electron micrograph (SEM) of a blood clot (centre) forming in connective tissue. Red blood cells (erythrocytes,red) are trapped within a fibrin protein mesh (purple threads). The fibrin mesh is formed in response to chemicals secreted by platelets (pink),fragments of white blood cells. Clots are formed in response to cardiovascular disease or injuries to blood vessels.
