• It moves blood through the body.

Glenn is looking at a diagram that illustrates an organ

If your blood glucose gets too low, your pancreas will secret glucagon that causes your liver to release more stored sugar into the blood. This is an example of

• negative feedback

• static equilibrium

• glycogen

If your temperature gets too high, your body will sweat and your blood vessels in your skin will dilate (open). The stimulus in this example is

• body temperature

• increase in body temperature

• sweat

• blood vessels dilating
