Across
- 3. the amount of blood pumped out of each ventricle in one minute (HR x SV)
- 6. material pressure that the heart is pumping against
- 7. a blood vessel that carries blood from the heart to tissues and organs in the body
- 12. the sound the closure of the pulmonary and aortic valves makes
- 14. "pacemaker" , controls the electrical impulses which cause contraction
- 15. the sound the closure of the AV valves makes
- 17. the largest artery in the body, carries O2-rich blood away from the heart to the rest of the body
- 21. a large vein that carries blood to the heart from other areas of the body
- 22. the fibrous strand that connect the papillary muscles to the mitral and tricuspid valves in the heart
- 23. the two lower chambers of the heart, one one the right and one on the left
- 24. volume of blood in the ventricle before contraction
- 26. the phase of the cardiac cycle when the heart muscle relaxes and the heart's chambers fill with blood
- 28. carries oxygen poor blood to the lungs and back to the heart
- 29. the contraction of the heart muscle that forces blood out of the heart and into the circulatory system
- 30. rapid and irregular signaling contractions not controlled by SA node, fixed by defibrillation
Down
- 1. flaps that open and close to control the direction and flow of blood through the heart
- 2. transmits the stimulus to the ventricles
- 4. delicate blood vessels that exist throughout your body
- 5. Volume / beat
- 8. a tiny vein, one that collects blood from the capillaries
- 9. uncoordinated atria; and ventricular contractions
- 10. all of the events involved with the blood flow through the heart
- 11. caused by high pressure in the ventricle by itself
- 13. channels that carry blood throughout the body
- 16. carries oxygen rich blood from the heart to the rest of the body and back
- 18. beats / minute
- 19. delays the stimulus to the ventricles
- 20. any of the tubing that forms the part of the blood circulation system of the body, mostly carries O2 poor blood to the heart
- 25. the two upper chambers of the heart that receive blood from the veins and pump it into the ventricles
- 27. distribute stimulus to the myocardial cells
