In a negative feedback system, ____.

A) the response of the integrator is aligned with the output of the effector
B) the effector brings the system back to the set point
C) a steady state condition cannot be maintained
D) the response of the integrator is opposite the input of the sensor
E) the resulting outcome is always greater than the input

Negative Feedback System

A regulatory system in which a change in some steady state triggers a response that counteracts, or reverses, the change, restoring homeostasis (e.g., how mammals maintain body temperature). Compare with positive feedback system.

Integrator

In homeostasis, a control center.

Effector

(1) A muscle or gland that contracts or secretes in direct response to nerve impulses. (2) In homeostasis, an organ or process that helps restore a steady state.
