8. Platelet
   Platelet: An irregular, disc-shaped element in the blood that assists in blood clotting. During normal blood clotting, the platelets clump together (aggregate). Although platelets are often classed as blood cells, they are actually fragments of large bone marrow cells called megakaryocytes.

9. platelet
   Anucleate discoid cell (3 m m diameter) found in large numbers in blood; important for blood coagulation and for haemostasis. Platelet a -granules contain lysosomal enzymes; dense granules contain ADP (a potent platelet aggregating factor), and serotonin (a vasoactive amine). They also release platelet-derived growth factor which presumably contributes to later repair processes by stimulating fibroblast proliferation.

    Tiny disc-shaped structure found in the blood, which helps it to clot. Platelets are not true cells, but membrane-bound cell fragments without nuclei that bud off from large cells in the bone marrow.
