Across
  1. 2. This is the largest organ in the body and an organ to which blood flow increases during exercise
  2. 3. Part of the cardiac cycle in which the heart muscle contracts, pumping blood out of the chambers
  3. 7. This organ receives the most blood flow at rest.
  4. 10. The activation of these types of nerves within the autonomic system decreases heart rate.
  5. 11. The part of the cardiac cycle in which the heart muscle relaxes, allowing blood to fill the chambers.
  6. 14. The name of the left AV valve
  7. 15. This is the type of muscle that blood will primarily flow to during exercise
  8. 16. A value that is calculated by multiplying heart rate and stroke volume (as one word).
  9. 18. The relaxation of this muscle type allows more blood to enter the capillary beds
  10. 19. The name of the right AV valve
  11. 20. What happens to vagal activity during exercise
Down
  1. 1. The name of the right semilunar valve
  2. 2. The activation of these types of nerves within the autonomic system increases heart rate.
  3. 4. Blood flow to this organ remains the same during periods of rest and exercise.
  4. 5. The sub-type of nervous system that controls heart rate in mammals.
  5. 6. An increase in heart rate corresponds to a shortening of this (as one word).
  6. 8. The circulating levels of this hormone affect stroke volume.
  7. 9. An organ that, along with the gut, receives 50% of blood flow at rest.
  8. 12. The name of the left semilunar valve
  9. 13. A value that can rarely exceed 180 BPM in human adults (as one word).
  10. 17. Most of the shortening of the cardiac cycle occurs during this phase (as one word).
