Homeostatis
Maintain body temp near an ideal normal value
Homeostatic mechanisms
Conditions that can change
Variables
Ideal value
Set point
Acceptable range of values on which HM can still be met
Normal Range
Regulates most systems of the body to maintain homeostatis
Negative
Negative-feedback mechanism
Not homeostatic, very rare in a healthy individual
Positive
Massive blood loss, child birth
Positive-feedback mechanism
