Questions and Answers

Which of the following is true regarding pressure changes in the heart during the cardiac cycle?

  • The pressure changes are equal in both sides of the heart.
  • The pressure changes in the right side of the heart are about 5 times greater than those in the left.
  • The pressure changes in the left side of the heart are about 5 times greater than those in the right. (correct)
  • The pressure changes in the right and left sides of the heart are not significant.
  • What is the difference between pulmonary and systemic circulation?

  • Pulmonary circulation is a high-pressure system and systemic circulation is a low-pressure system.
  • Pulmonary and systemic circulation have the same pressure
  • Pulmonary circulation is a low-pressure system and systemic circulation is a high-pressure system. (correct)
  • Pulmonary and systemic circulation do not involve pressure changes.
  • What are typical systolic and diastolic pressures in the aorta?

  • 80 and 120 mmHg, respectively.
  • 8 and 24 mmHg, respectively.
  • 120 and 80 mmHg, respectively. (correct)
  • 24 and 8 mmHg, respectively.
  • Study Notes

    • Systole and diastole are contraction and relaxation periods of the heart.
    • The cardiac cycle includes all events associated with blood flow through the heart during one heartbeat.
    • Pressure and volume changes occur in the heart during the cardiac cycle.
    • Pressure changes in the left side of the heart are about 5 times greater than those in the right.
    • Each ventricle pumps the same volume of blood per beat.
    • The length of the cardiac cycle is approximately 0.8 seconds.
    • Blood flow through the heart is controlled by pressure changes and flows along a pressure gradient.
    • Pulmonary circulation is a low-pressure system and systemic circulation is a high-pressure system.
    • Typical systolic and diastolic pressures for the pulmonary artery are 24 and 8 mmHg, respectively.
    • Typical systolic and diastolic pressures in the aorta are 120 and 80 mmHg, respectively.
