E

e.g. burning hand on stove

Variable chemical/physical property that may change

Receptor sensory receptors send info to brain and monitor variables

Control Center recieves input sends response if needed

Effector takes neccessary action to correct imbalance

Negative feedback

achieves a goal 

a series of events that ultimatley opposes or negates intitial change

e.g.body temp regulation

skin senses its hot

sends message to brain its hot

brain gets message and tells body to sweat

message returns to skin and you sweat

Positive feedback

Amplifies events

restores homeostasis
