The mechanisms by which a constantinternal environment is achieved. The stability attained is a dynamic equilibrium, in which continuouschangeoccurs yet relativelyuniformconditions prevail.
What is negative feedback?
The response when conditionschange from the ideal or setpoint which returns conditions to this setpoint. There is a continuouscycle of events
What is positive feedback?
When a high level of something triggers the body to increase it even further
Positive feedback is rare in biological systems since it leads to an unstablesituation and extreme states. A disturbance leads to events which increase the disturbancefurther e.g nervepropagation
