(6.4) Homeostasis Basics
-
negative feedback
-
only works within certain limits, if the change is too big, effectors may not be able to counteract it. e.g. huge, sudden drop in body temp
-
having multiple negative feedback systems mean the body can have more control over changes - can actively increase/decrease levels according to a situation
-
homeostatic systems
involve receptors, communication system & effectors
-
-
-
positive feedback
-

-
hypothermia
-
-
as temp falls, brain doesn't work properly & shivering stops - body temp falls even more
positive feedback takes body temp further away from normal and continues to do so until action is taken
