  1. 4. When strenuous exercise is performed, a ________ heart rate is reached.
  2. 7. Cardiac output can increase from approx ______ litres per min for an adult at rest up to approx 35 litres per min for a highly trained adult.
  3. 10. This is the greatest volume of air that can be expired after a maximum inspiration.
  4. 11. Gas exchange takes place in the millions of alveoli and the _________ that surround them.
  5. 12. Maximum heart rate can be estimated for any individual with the simple equation 220 - _______?
  6. 13. Increased stroke volume occurs during exercise due to more ________ blood being returned to the heart.
  7. 16. The amount of blood the heart pumps out with each beat.
  8. 18. This increases during exercise due to the fact that blood is travelling through the vessels at a faster rate.
  9. 21. Both tidal volume and ________ ________ increase during physical activity to meet the demand for more oxygen.
  10. 22. During strenuous activity, the oxygen concentration in the ________ remains the same, however the venous oxygen concentration drops dramatically.
  11. 23. All of the body's cardiovascular responses to exercise are based around getting more of this to the working muscles.

  1. 1. The elevation in heart rate is directly proportional to the ________, up to a limit.
  2. 2. The most amount of oxygen that a person can use during exercise is known as ________.
  3. 3. People with a greater __________ endurance also have a greater VO2max.
  4. 5. When the muscles take more oxygen from the blood during sport and exercise, this is known as increased oxygen ________.
  5. 6. The exchange of gases in the lungs increases up to three times as much during strenuous exercise compared to resting levels.
  6. 8. The rate at which the heart beats ________ during exercise and sport.
  7. 9. This is the amount of air that is inspired and expired by the lungs at rest or exercise.
  8. 14. The total amount of blood circulated around the body per minute.
  9. 15. Increased stroke volume is also accompanied by stronger heart ________.
  10. 17. The extent of the body's responses during exercise is dependent upon the intensity and _________ of the exercise.
  11. 19. Respiratory rate can increase during exercise from approx 12 breaths per min to approx ______ breaths per min.
  12. 20. Cardiac output can be calculated by multiplying ________ ________ by stroke volume.
