Across
  1. 3. These muscles have the most amount of blood flow during exercise
  2. 10. Stimulation of these nerves increase the heart rate
  3. 11. This interval indicates the time that ventricles take to relax and fill
  4. 13. This heart sound is heard during systole
  5. 14. These valves separate the arteries and the ventricles
  6. 16. Which heart sound is caused by the closing of the semilunar valves
  7. 18. This term is the volume of blood the heart pumps each minute (one word)
Down
  1. 1. This measurement is increased during moderate exercise and takes significant time of recovery to return to normal levels pre-moderate exercise
  2. 2. This wave is caused by atrial depolarization
  3. 3. Which node acts as a pacemaker
  4. 4. These valves separate the atrium and the ventricles
  5. 5. means contraction; indicates the heart contracting and pumping blood from chambers to arteries
  6. 6. How many heart valves are in the heart
  7. 7. Means relaxation; indicates the filling of the heart chambers through relaxation of the heart muscle
  8. 8. Stimulation of these nerves decrease the heart rate
  9. 9. Someone who rarely exercises will have, on average, a ‘blank’ heart rate
  10. 12. This measure is on average lower for individuals who work out more
  11. 15. This interval increases due to an increase in heart rate (one word)
  12. 16. Can increase up to 1.5 times its normal amount during exercise to allow for greater cardiac output
  13. 17. This wave is caused by ventricular repolarization
