Homeostasis

• allows for a wildly fluctuating internal environment

• is impossible in vertebrates

• is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation

• is the maintenance of a relatively stable external environment and often incorporates a form of feedback regulation
