Across
  1. 2. heart valve between the right atrium and right ventricle
  2. 3. outermost layer of the heart wall; aka visceral pericardium
  3. 14. blood vessel that carries blood from the heart to the body
  4. 15. fast heart rate
  5. 16. delays the signal from the SA node slighly
  6. 17. delivers blood to the left ventricle
  7. 18. allows one-way blood flow through the heart
  8. 19. related to the body
  9. 20. contains serous fluid outside the heart
  10. 21. muscle layer of the heart wall
  11. 23. innermost layer of the heart wall
  12. 25. muscle that pulls on cusps via tendons
  13. 26. "pacemaker" cells within the right atrium
Down
  1. 1. location of the AV bundle
  2. 4. delivers needed blood to cells of conducting system
  3. 5. collects blood from the right atrium
  4. 6. abnormal heart rhythm
  5. 7. cavity located between lungs; contains heart
  6. 8. slow heart rate
  7. 9. ventricles relax
  8. 10. division of the nervous system that helps control the heart rate
  9. 11. blood vessel that delivers blood from the body to the heart
  10. 12. ventricles contract
  11. 13. normal rhythmic series of heart contractions
  12. 22. subdivision of the AV bundle that deliver impulse to the ventricles to contract
  13. 24. related to the lungs
