When ventricular pressure exceeds atrial pressure, the
A) ejection occurs.
B) atria pump blood into the ventricles.
C) ventricle is in diastole.
D) blood is pumped into the atrium.
E) AV valves close.
Ventricular Pressure
The pressure within the heart's ventricles during the cardiac cycle, crucial for pumping blood throughout the body.
Atrial Pressure
The pressure within the atria of the heart, indicating the volume of blood returning to the heart and influencing heart function.
Ejection
The process of driving or pushing something out.

Final Answer :
E
Explanation :
When ventricular pressure exceeds atrial pressure, the atrioventricular (AV) valves (mitral and tricuspid valves) close to prevent the backflow of blood into the atria. This event marks the beginning of ventricular systole.
