Unformatted text preview: e things that anticipate the change.
ex: if you suddenly exercise a lot or if you have to rush to
somewhere, there are anticipatory changes: so you
increase respiration before there's a change in oxygen
(anticipating the change so you can minimize the change
when it occur) 2. The “set point” of control systems can be altered
there are redundancy. They are all anatomically active. 3. Controls are often redundant and antagonistically arranged
Homeostatic mechanism is not static. At one time, not just have negative feedback but also have
positive feedback control. There are feedback as well as feedforward system.
Feedback system is changes to system after change occur. 4. Feedforward systems anticipate changes before they occur
5. Positive feedback causes changes in state positive feedback is rare but occur.
