Document Summary
Provide examples for each type: homeostatic mechanisms, negative feedback: counteracts any change (anything acting against the set point/normal range) Control center: tells your body how to react to situation, ex: hypothalamus. "set point" - how to tell what the balance is: ex: temp is 98. 6. Effector: coping mechanism, ex: cold weather causes you to shiver.
