Questions and Answers

What happens to ventricular pressure during late diastole?

  • Ventricular pressure rises slightly during inflow of blood from atrial contraction (correct)
  • Ventricular pressure falls further to below 5 mm Hg
  • Ventricular pressure increases significantly
  • Ventricular pressure remains constant

    • Which valve is open during systole to allow ejection of blood from the left ventricle?

  • Aortic valve (correct)
  • Pulmonic valve
  • Mitral valve
  • Tricuspid valve

    • Which valve is closed during diastole to prevent regurgitation of blood from the aorta back into the left ventricle?

  • Aortic valve (correct)
