Isovolumetric relaxation ends immediately after________________?
Correct answer: D. When ventricular pressure falls below atrial pressure
- A. AV Valve closes
- B. When ventricular pressure falls below aortic pressure
- C. None of the aboveConsult Online Doctors
- D. When ventricular pressure falls below atrial pressure
Explanation
Isovolumetric relaxation ends when ventricular pressure falls below atrial pressure, allowing the atrioventricular valves to open and ventricular filling to begin. The semilunar valves have already closed at the start of this phase.
