Across
  1. 5. this kick provides 15-30% of ventricular filling
  2. 6. this nervous system increases heart rate and blood pressure
  3. 8. amount of blood pumped by the heart every minute
  4. 9. these cells create and conduct electrical signals to tell the heart when to beat
  5. 10. this nervous system slows the heart rate and decreases blood pressure
  6. 11. these valves separate a ventricle from an artery
  7. 14. layer of the heart that contains the conduction system

  9. 18. double-walled sac that encloses the heart
  10. 19. chest cavity
Down
  1. 1. innermost layer of the heart
  2. 2. these cells cause the heart muscle to contract
  3. 3. fluid in between the layers of the heart that minimizes friction
  4. 4. breastbone
  5. 6. muscular band of tissue that divides the heart into right and left sides
  6. 7. layer of the heart that contains the coronary arteries
  7. 12. layer of the heart that is muscle and is damaged during a heart attack
  8. 13. this cycle refers to the mechanical events that occur to pump blood
