Which of the following is a function of your circadian rhythm?

When a jogger starts to run, the rate at which his muscles produce CO₂ rises sharply. But the CO₂ in his blood rises only slightly before he starts to breathe faster and his heart starts beating stronger. Soon his increased rate of CO₂ production is balanced by an increased rate of CO₂ removal. This would be an example of __________ feedback because the jogger's circulatory and respiratory systems are __________.

What kind of feedback most directly maintains homeostasis? Why is this?
