The average number membership of an American mosque was 1,248 in 2011, which counts Muslims who at least pray for Eid-al-Fitr, one of two major holidays, at the mosque. That's down from 1,625 in 2000 and is likely because of a growth in the number of mosques.
Platelet Function The role of blood platelets is to clog broken blood vessels to prevent the loss of blood. Under normal conditions, platelets move through blood vessels in an unactivated state.

The haemostatic role of platelets was established in the 1880s by Bizzozero who observed their ability to adhere and aggregate at sites of vascular injury.It was only some 80 years later that the function of platelets in maintaining the structural integrity of intact blood vessels was reported by Danielli.nterestingly, from a mechanistic point of view, the supporting role of platelets in these various vessels does not necessarily involve the well-understood process of platelet plug formation but, rather, may rely on secretion of the various platelet granules and their many active components.
