Question

Match the pressure relationships, labelled a. through e., with the times in question. (Options may be used more than once or not at all.)
-when ventricular ejection is occurring
A)aortic pressure > ventricular pressure > atrial pressure
B)ventricular pressure > aortic pressure > atrial pressure
C)aortic pressure > atrial pressure > ventricular pressure
D)ventricular pressure > atrial pressure > aortic pressure
E)atrial pressure > ventricular pressure > aortic pressure

Quizplus · Accepted Answer

During ventricular ejection, the ventricular pressure exceeds aortic pressure, causing the aortic valve to open, allowing blood to flow into the aorta. Atrial pressure remains low during this phase. Thus, ventricular pressure > aortic pressure > atrial pressure.
