1. Explanation of change in heart rate during exercise.

What is the mechanism to explain the change in heart rate when exercise begins?

Include reference to the receptors and their location, the part of the brain acting as the control centre, and the nerves which transmit the impulses from brain to heart)

2. Why does the heart rate change during exercise with respect to transport of gases?

(What are the two principal gases, where are they transported from and to AND why does the heart rate have to change during exercise?)

3. Why does the heart rate change during exercise with respect to transport of the nutrient glucose?

(Where does the glucose need to be transported from and to and why are different amounts needed during exercise?)

4. Why does the heart rate change during exercise with respect to transport of heat?

(Where is the heat being generated, where does it need to be transported to and how do changes in the circulatory system enable heat to be lost from the body?)
