Question

Quizplus · Accepted Answer

During ventricular systole, the heart undergoes two main phases: isovolumetric ventricular contraction (C) where the ventricles contract with no volume change because all valves are closed, and ventricular ejection (D) where blood is pumped out of the ventricles as the pressure rises and exceeds that in the arteries, leading to the opening of the outflow valves.
