WebbPlatelets are key players in haemostasis, the process by which the body seals a ruptured blood vessel and prevents further loss of blood. Although rupture of larger vessels usually requires medical intervention, haemostasis is quite effective in dealing with small, simple wounds and small internal bleeds. Platelets are blood cells that are released from bone marrow megakaryocytes and circulate for approximately 10 days. They possess granular cytoplasm with no nucleus and their diameter when seen in a Wright-stained peripheral blood film averages 2.5 um with a subpopulation of larger cells, 4–5 um.
