Injury to the endothelium or inner lining of a vessel activates platelets, this aggregates on the injured site and activates formation of fibrin from plasma and the fibrin traps red blood cells forming a plug. Granules in the platelet surface degranulates loosing its products which activates vasoconstriction mechanism to the injured site thus causing bleeding cessation.
