a.
b.
c.
d.
Correct.
Incorrect.
3. How do you expect the heart rate to change if a person switches from jogging to sprinting?
a. Stay the same, as the person is exercising in both cases
b. Decrease, as the person increases the intensity of the exercise
c. Increase, as the person increases the intensity of the exercise
Correct.
Incorrect.
4. Why does our heart help us to survive by being able to quickly increase our heart rate?
a. A quick increase in heart rate helps us to build muscles fast, and thus, get stronger.
b. A quick increase in heart rate helps us to react to danger quickly, as it delivers extra oxygen to the muscles and organs, which in turn, leads to an increase in energy and alertness.
c. A quick increase in heart rate helps to relax the muscles and give them the rest they need.
Correct.
Incorrect.
5. In your own words, state why we can measure the heart rate by feeling the pulse. How does this connect with what we know about the function of the heart?
