Positive feedback mechanism. A process whereby an initial change in an atmospheric process will tend to either reinforce the process (positive feedback) or weaken the process (negative feedback). See Feedback mechanism.
It is a positive feedback mechanism because each contraction stimulates the release of more oxytocin which, in turn, makes the next contraction start sooner and become str â¦ onger.
