RFPR1T4X–Activated platelets, coloured scanning electron micrograph (SEM). Platelets are blood cell fragments that play an essential role in blood clotting and wound repair, and can also activate certain immune responses. They are formed in the red bone marrow, lungs, and spleen by fragmentation of very large cells known as megakaryocytes. Platelets in the blood are small oval disks and are termed non-activated platelets or thrombocytes. They are the body's first line of defence against excessive blood loss. Magnification: x2,000 at 10 cm wide.
