• homeostasis

If the environment gets cold, we will often shiver in order to:

• keep body temperature the same as the external temperature

Negative feedback loops ...

• are one way an organism can maintain homeostasis.

• are rarely found in healthy individuals

• respond by making deviations from normal even larger

• cannot be counteracted with medicine
