Homeostasis

• allows for a wildly fluctuating internal environment

Multiple Choice

When you get cut, your skin cells release hormones that signal platelets to come and stop the bleeding. Platelets then release more hormones that signal even more platelets to help stop bleeding. The hormone signals continue until the cut is closed.
