By Shane Kelleher, Tommy Stein, and Daniel Coyle.. What are platelets?. Platelets are tiny particles of blood that help form blood clots. Blood clots are essential to humans to help prevent extreme blood loss. Thrombocytes. Platelets (Thrombocytes). 2- 4 micromillimeters in diameter. 250,000 – 400,000 per microliter . (too few thrombocytopenia – too many thrombocytosis). Lifespan on average 6 – 10 days. Acquired coagulation disorders:. They are . more common. than the inherited disorders.
