All of the following are true regarding a normal cardiac cycle except
O the aortic valve closes when left ventricular pressure falls below aortic pressure
O the ventricles receive 70% of the blood from the atria passively during ventricular diastole
the atria and ventricles are both in diastole for a brief period of the cardiac cycle
Othere is a point where the atrioventricular and semilunar valves are open at the same time
