87
patho of sick cell anemia
elongated RBC that for sickle shape, increases blood viscosity, accumulation in the smaller blood vessels leads to obstruction then tissue death

patho for DIC
extensive thrombin enters systemic circulations and overwhelms natural anticoagulant. wide spread clotting consume clotting factors and activates fibrinolytic process with anticoag productions causes hemorrhage
