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.
There are two types of feedback, negative and positive feedback. Negative feedback is most common in biological systems, for example: doing excercise creates metabolic heat which raises the core temperature of the body, then due to cooling mechanisms such as flushed skin or sweatingbegin and the temperature decreases.ositive feedback kicks in when rapid change is needed. An example of this is when the hormone oxytocin in childbirth is produced to stimulate and enhance labour contractions. (Homeostasisâ Part 1: anatomy and physiology, Â©2012). Below picture shows the stages in a negative feedback system.
