Thermoregulation is a feedback mechanism because it

• increase blood glucose levels

• restores normal breathing rates

• restores homeostasis

• decreases carbon dioxide levels in the blood

Why is the inability to sweat (anhidrosis) dangerous?

• It results in high blood glucose.

• It can lead to high blood pressure.

• It prevents your body from cooling down when it's too hot.

• It helps your body regulate carbon dioxide levels.

Why is blood clotting an important feedback mechanism?

• It decreases the amount of blood in your body.

• It prevents you from bleeding to death.

• It helps you to regulate body temperature.

• It increases blood glucose levels.
