What occurs during passive ventricular filling?

Explanation:
During passive ventricular filling, the ventricles are relaxing and their pressure drops below that of the atria. This pressure difference opens the atrioventricular valves, allowing blood to flow from the atria into the ventricles without requiring atrial contraction. This passive flow occurs mainly in early diastole as the heart relaxes. The other choices describe events tied to ventricular systole (contraction and ejection) or to valve closure, which are not what happens during passive filling.
