Activated platelets. Coloured scanning electron micrograph (SEM) of platelets (thrombocytes,blue) that have been activated. Platelets are part of the blood. When a blood vessel is damaged,the platelets become activated and secrete chemicals that cause the formation of a fibrin mesh. This mesh traps platelets and red and white blood cells,forming a clot that seals the damaged blood vessel | |
