Blood clot. Coloured scanning electron micrograph (SEM) of red blood cells (erythrocytes) trapped in a fibrin mesh (green). The production of fibrin is triggered by cells called platelets,activated when a blood vessel is damaged. The fibrin binds the various blood cells together,forming a solid structure called a blood clot. A blood clot is a normal response,preventing an excessive loss of blood. However,inappropriate clotting is a major cause of heart attacks and strokes | |
