Across
  1. 1. This node delays the signal to keep the heart beating rhythmically
  2. 3. Decreases arterial volume, which decreases blood pressure
  3. 4. The artery supplies blood to the upper extremities
  4. 5. The myocardium receives its blood supple from these arteries
  5. 6. This artery supplies blood to the gut
  6. 8. The S2 sound when the aortic and pulmonic valves close
  7. 9. This artery supplies blood to the lower extremities
  8. 11. Atrial contract during this phase of the cardiac cycle
  9. 13. Initiates the signal for the heart to contract
  10. 14. This artery supplies blood to the brain.
  11. 15. Stroke volume times HR over one minutethe heart in one minute.
  12. 16. Contraction of the ventricles, forcing blood into the aorta and pulmonary artery
  13. 18. Carries signals up through the ventricles, stimulating contraction from the bottom upwards
  14. 19. The innermost layer of the heart
Down
  1. 2. Increases arterial volume, which increases blood pressure
  2. 7. Conveys the signal to the apex of the heart
  3. 10. One complete sequence of heart contraction and relaxation
  4. 12. The S1 sound when the tricuspid and mitral valves close
  5. 17. The volume of blood pumped from the left ventricle per beat
