As you get dehydrated, your blood becomes thicker and harder to pump. Your kidneys will respond by stopping urine production, sending the water from urine into your bloodstream to thin your blood back to normal level. This is an example of what type of feedback?
Positive Feedback Response
Negative Feedback Loop

Positive Feedback Response
Negative Feedback Loop
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. This is an example of what type of feedback?
