increasing afterload
  • Which of the following would decrease stroke volume?
  • Which valve is located between the right atrium and ventricle?
  • What does the QRS wave of the ECG represent?
  • Which of the following descriptions does not describe atrioventricular (AV) valves?
left atrium
  • What structures connect the individual heart muscles cells?
  • Which of the following would decrease stroke volume?
  • Which valve is located between the right atrium and ventricle?
  • Which heart chamber receives oxygenated blood from the lungs?
AV node
  • Which of the following structures receives the depolarization wave from the atria and passes impulses onto the ventricles?
  • Which valve is located between the right atrium and ventricle?
  • Which of the following descriptions does not describe atrioventricular (AV) valves?
  • Which of the following would decrease stroke volume?
back pressure exerted by arterial blood
  • What best describes after load?
  • What does the QRS wave of the ECG represent?
  • What causes heart sounds?
  • Which best describes the isovolumetric contraction phase of the cardiac cycle?
As ventricular systole starts, the AV valves are closed and the semilunar valves are closed. Because the ventricle are contracting and both valves are closed, pressure increases rapidly leading to ejection.
