Across
  1. 8. carry blood away from the heart
  2. 9. takes place in mid-to-late diastole
  3. 11. is continuous with endothelial lining of blood vessels
  4. 12. smaller diameter fibers; fewer gap junctions
  5. 13. relaxation
  6. 14. carry blood toward the heart
  7. 15. generates impulses about 75 times/minute
  8. 16. on the external surface of the heart
  9. 17. only electrical connection between the atria and ventricles
Down
  1. 1. visceral layer of the serious pericardium
  2. 2. lines the internal surface of the fibrous pericardium
  3. 3. contraction
  4. 4. ventricles relax
  5. 5. complete the pathway into the apex and ventricular walls
  6. 6. spiral bundles of cardiac muscle cells
  7. 7. atria relax and ventricles begin to contract
  8. 10. prevent backflow into ventricles when ventricles relax
