, Organ level - CORRECT ANSWER -
combination of tissues of differing types to carry out a particular function
Negative feedback - CORRECT ANSWER -
a reaction that causes a decrease in function; essentially reduces, shuts off, or counterbalances the ori
ginal stimulus that caused the homeostatic imbalance
-
causes the given variable to change in the opposite direction of the inital change, and brings the syste
m back to homeostasis
- ex: temp, blood glucose levels, blood volume, ph, composition
Positive feedback - CORRECT ANSWER -
the response of the effector works to further increase the change that was caused by the stimulus; ma
y enhance, exaggerate, or amplify the original stimulus
- ex: childbirth, blood clot formation, menstrual cycle
