Across
  1. 2. microscopic blood vessels where gas exchange occurs at the alveoli and body cells (including muscle fibres)
  2. 3. exercise intensity that can be maintained up to but not exceeding 85 percent of your maximum heart rate
  3. 4. the circuit of flow that goes to the body and back to the heart
  4. 7. the force of your blood on your artery walls in between beats, during heart relaxation
  5. 9. the body system made up of the heart, blood and blood vessels with the primary function of transporting oxygen and nutrients
  6. 10. Tiny air sacs at the end of the bronchioles(tiny branches of air tubes in the lungs)where the lungs and the blood exchange oxygen and carbon dioxide
  7. 13. the narrowing of blood vessels supplying the other organs resulting in reduced blood flow where oxygen demand is lower
  8. 14. the force of your blood on your artery walls during heart contraction
  9. 17. the volume of blood ejected from the left ventricle each beat measured in ml/beat
  10. 19. the total volume of air breathed in and out of the lungs in one minute (L/min)
  11. 20. the number of time the heart contracts in one minute measured in bpm
  12. 21. blood vessels carrying deoxygenated blood back to the heart from the body
  13. 24. the maximum number of beats your heart can make per minute normally achieved during incremental exercise such as a VO2Max test
  14. 27. the total number of breaths taken in one minute (breaths/min)
  15. 28. the body's immediate, short term changes that occur in response to exercise. usually to increase oxygen uptake
  16. 29. blood vessels carrying oxygenated blood away from the heart to the working muscles
Down
  1. 1. the maximum volume of oxygen that the body is using for aerobic ATP (energy) production achieved during incremental exercise to exhaustion
  2. 5. where more blood flow is redirected to the working muscles and less of it goes to other body organs such as the digestive system
  3. 6. term used to describe a straight-line relationship between two variables such as heart rate and exercise intensity
  4. 8. the difference in oxygen content between the arteries and veins
  5. 11. the widening of blood vessels supplying the other organs resulting in increased blood flow where oxygen demand is higher
  6. 12. the force of your blood on your artery walls
  7. 15. the movement of gases (including oxygen and carbon dioxide) between the alveoli (lungs) and the capillaries (blood)
  8. 16. the number of time the heart contracts in one minute while at rest
  9. 18. the increase in HR in the minutes before exercise commences, usually due to anxiety and adrenalin
  10. 22. the total volume of air breathed in and out of the lungs in one breath(L/breath)
  11. 23. the total volume of oxygen that the body is using for aerobic ATP (energy) production
  12. 25. the volume of blood ejected from the left ventricle per minute measured in L/min
  13. 26. o reach a state or level of little or no increase or decrease; to remain at a stable level or to level off
