6. HR X SV calculates...

  • stroke volume
  • cardiac output
  • heart rate

7. Where does gas exchange take place?

  • Venules
  • Heart
  • Capillaries
  • Arterioles

8. Heart rate is 220 - your age

  • True
  • False

9. What is atherosclerosis?

  • Blockage of arteries
  • Changes in the lining of arteries when fat and cholesterol accumulate
  • Vasodilation and vasoconstriction of arteries

10. What is heart rate (HR)?

  • volume of blood ejected from heart per minute
  • number of beats per minute

  • Coronary artery

14. The diastole and systole are phases in the cardiac cycle

  • True
  • False

15. What is arteriosclerosis?

  • loss of elasticity, thickening and hardening of arteries leading to vasodilation and vasoconstriction
  • accumulation of fat and cholesterol causing changes in lining of arteries

16. 5l/min is the rest value for

  • SV
  • Q
  • HR

17. Angina is the blockage of which type of artery?

  • Coronary
  • Pulmonary

18. What is hypertrophy?

  • increase in the size of the heart muscle which increases SV and decreases resting HR
  • slowing down of the heart rate, therefore the heart is under less strain at rest
