What is the function of the ventricles during systole?

Explanation:
During systole the ventricles contract and pump blood into the pulmonary artery and the aorta. This contraction raises ventricular pressure, opening the semilunar valves to eject blood while the atrioventricular valves close to prevent backflow. The other options describe processes that occur at different times or aren’t the ventricles’ primary action in this phase: atrial contraction happens during atrial systole, ventricular filling occurs during diastole, and simply “valves open” doesn’t capture the ventricles’ main pumping function.
