• solar feedback loop

• the muscles

• negative feedback loop

When CO2 levels become too high in our blood, we begin to breathe faster. In this example, our diaphragm and intercostal muscles are

• the stimuli

• the response

• the effectors

• the neurons

Why is it important to maintain a constant body temperature?

• to stop the multiplication of bacteria in the body

• so that we don't get cold

• to maintain the optimum temperature for enzymes

• so that we have enough energy to move
