water leveks and others.
Negative feedback
Counteracts changes
Receptor detects a stimulus-level is too high, the
coordination center recieves and porcesses this
information and then organises a response,
Effector produces a response which counteracts
the change and restores the optimum level- the
level decreases.
Receptor detects a stimulus- level is too low,
the coordinator center receives and
processes the information then organises a
response, Effector produces a response which
counteracts the change and restores the
optimum level- the level increases.
What are Effectors?
The effector carry on producing the
responce for as long as they're
simulated by the coordination centre.
This might causes the oppposite
problem- making the level change too
much (away from the idea). Luckily the
receptor detects if the level becomes
too different and the negative feedback
response starts again.
