5. set point


negative feedback - CORRECT ANSWER - mechanism that exists as a
feedback loop because it can either increase or decrease the stimulus. will
perform the opposite of the stimulus in order to return to homeostasis. (ex.

positive feedback - CORRECT ANSWER - maintains the direction of the
stimulus, possibly accelerating it. (ex. Blood clotting/coagulation - as one
clotting factor is activated, it activates the next factor in the sequence until a
fibrin clot is achieved) (ex. Human birth - pressure on cervix, contractions,
hormone secretion)


Homeostasis - CORRECT ANSWER - "steady state"; ability to maintain
