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

Maintaining body temperature is an example of a:

• negative feedback loop
• positive feedback loop

What is positive feedback (in homeostasis)?

• When the body has an infection

• When the body responds to a stimulus and then stops the response when things are back to normal

• When the body responds to a stimulus by continuing to increase something

• When the body does not respond to a stimulus

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.

• Positive Feedback Response
• Negative Feedback Loop
