maintanenace
step 1
stimulus: produces change in variable
step 2
change detected by receptor
step 3
input: information sent along different pathway to control centre
stop 4
Output: information sent along efferent pathway to effector
step 5
response of effector feeds back to influence magnitude of stimulus and returns variable to homeostasis
