Accepted Answer

Ventricular systole refers to the contraction of the ventricular myocardium. During this phase, the ventricles contract and blood is pumped out into the pulmonary and systemic circulation. Choices A and B refer to earlier stages of the cardiac cycle, and choice C refers to the filling of the ventricles, which occurs during diastole.
