Final answer:

During ventricular systole, the ventricles contract to push blood out of the heart while the AV valves are closed.


Explanation:

Ventricular systole is the phase of the cardiac cycle when the ventricles contract, forcing blood out of the heart. During ventricular systole, the atrioventricular (AV) valves are closed to prevent backflow of blood into the atria.
