Question

Quizplus · Accepted Answer

Ventricular systole is the phase of the cardiac cycle when the ventricles contract and push blood out of the heart. During this phase, the atrioventricular valves close (A), pressure in the ventricles rises (D), and the semilunar valves open (E) to allow blood to leave the heart. The heart is not relaxed (B) during ventricular systole.
