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