  1. 1. When the left ventricle contracts, oxygenated blood flows through the___ valve.
  2. 4. Doc McStuffins wears a___ to listen to her patient’s heart sounds.
  3. 6. Periods of ventricular and atrial relaxation.
  4. 8. Heart beats too fast at rest (>100 bpm) causes___
  5. 12. When the left atrium contracts, blood is pushed through the… valve.
  6. 15. Deoxygenated blood is turned into oxygenated blood when it is delivered to the___ and then returned into the left atrium.
  7. 16. The ___ phase of an action potential in contractile cells of the myocardium, is in response to an influx of calcium ions.
  8. 19. Electrocardiogram records the ___ Activity of the heart.
  9. 20. The left ventricle is a ___ pressure system that pumps blood via the aorta.
  10. 21. Cardiac___ is defined as disorders of heart rhythms or heart rate.
  11. 22. Muscular layer of the heart that contracts.
  12. 23. Our body’s “fight or flight” response is the activation of our… nervous system.
  13. 24. The primary cardiac pacemaker:
  14. 28. The most common heart valve disorder, ___ Valve Prolapse occurs when the valve connecting the left atrium and ventricle do not function to close properly.
  15. 30. Refers to the pressure the ventricles of the heart need to overpower to pump blood into the arteries.
  16. 32. In Frank-Starling Law of the Heart states that the higher of a ___/EDV correlate to a higher stroke volume.
  17. 34. In concerns to fetal blood, the___ is responsible for oxygenating blood and removing CO2.
  18. 37. Cardiac myocytes (muscle cells of the heart) depend on ___ respiration.
  19. 39. The septum which separates the two atria of the heart.
  20. 40. The phase of the cardiac cycle which allows for contraction of the heart muscle and pumps blood out of the chambers is known as:
  21. 41. When the AV valves close, the heart makes this noise:
  22. 42. This heart defect occurs in 1 in 1500 births. It is caused by a narrowed aorta that pushes the left ventricle in working overtime: _____ of the aorta.
  23. 43. Cardiac muscle differs from skeletal muscle as cardiac muscle contains ___ Disks.
  24. 44. Contractility rises when more ___ penetrates the cytoplasm of the muscle.
  25. 45. The amount of blood held within the ventricles at the end of diastole is referred to as: ___ Diastolic Volume.
Down
  1. 2. The fourth phase of the cardiac cycle is known as___ relaxation. This occurs when the myocardium relaxes and allows for ventricular filling.
  2. 3. The narrowing of valves that prevents blood from flowing through is referred to as___
  3. 5. Heart beating too slow (<60 bp) is also known as:
  4. 7. The posterior surface of the heart is drained into the coronary sinus through the___ cardiac vein.
  5. 9. The QRS-complex displays the ___ myocardium depolarization of the heart.
  6. 10. The T-wave corresponds to ventricular myocardium ___
  7. 11. Blood is forced back into the atrium when valve leaflets do not properly close. This is referred to as:
  8. 13. A heart attack is the sudden and complete blockage of blood flow/artery to the heart, which is also referred to as myocardial___
  9. 14. When using a stethoscope, an abnormal third sound may be produced in response to a valve not closing completely.
  10. 17. ___ ionotropic agents permit an increase of contractility.
  11. 18. These events occur as a response to electrical events in the heart.
  12. 25. Unlike the lungs, where the apex is superior to the base; the heart’s apex is ___ to its base.
  13. 26. Cardiac ___ occurs when the heart is compressed with fluid within its sac.
  14. 27. The detection of low blood pressure that is caused by low blood volume are through:
  15. 29. This electrical activity of the heart is hidden behind the QRS wave and not present on an ECG. Also known as ___ myocardium repolarization.
  16. 31. Atrial ___ is characterized by the irregular and rapid heartbeat of the atria.
  17. 33. The superior and inferior vena cava delivers___ blood into the right atrium.
  18. 35. The regulation of the involuntary movements of the body, such as the heartbeat is the responsibility of the ___ Nervous System.
  19. 36. Heart Rate x Stroke Volume= ___ Output
  20. 38. Once the lungs become functional after birth, the foramen ovale closes and leaves behind a remanent referred to as the ___ ovalis.
