the study of the function of the body's parts and how the parts interact with each other


i.e=what a parts does

there are 2 mechanism that help us maintain homeostasis

1 negative feedback mechanism


i.e= change in temp. the temp. goes down the body responds by shivering to increase the temp.


2.positive feedback mechanism


i.e=the body responds in the same direction as the stimulus. blood clotting, labor contractions

negative feedback is the most common way to maintain homeostasis. it is used to maintain:

1=body temperature


2=blood glucose levels


3=blood ph levels


4=blood co2 and o2 levels


5=blood pressure
