homeostasis
maintenance of stable internal conditions
positive feedback
responds to a stimulus by making it more extreme. Ex. blood clot, your body keeps sending platelets to the wound to stop the blood flow.
steps of homeostasis
1)Stimulus2)receptor3) input sent down afferent pathway 4) control center 5) Output sent down efferent pathway to an effector 6) Response of the effector to the output
