<span>the positive feedback mechanisms used to accelerate the output that is created by an already activated stimulus during homeostasis, the positive feedback moves levels out of the normal ranges it should usually be found. From this explanation the view provided by the positive feedback mechanism is a negative useless mechanism, but one importance of this mechanism is that it help in the bodies accumulation of blood platelets. Therefore it acts in the healing of tears and breaks in blood vessels as the blood clots.
