Which of the following is an example of positive feedback to indirectly maintain homeostasis?

• the chemical reactions involved in blood clotting
• your blood vessels dilate and you begin to sweat in response to elevated body temperature
• your blood vessels constrict and you begin to shiver in response to low body temperature

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

Homeostasis in the human body is often maintained by a: 

• neutral feedback loop 
• solar feedback loop
• positive feedback loop
• negative feedback loop

Positive feedback is when the change caused by the stimulus is

• decreased
• non existant
• increased
• changes constantly

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

When you are cold, you shiver and your blood vessels contract, which warms you up. When you are hot, you sweat and your blood vessels expand, which cools you down.  

• Positive Feedback Response
• Negative Feedback Loop
