In the phase sequence, which phase is the fourth phase?

Explanation:
In the cardiac cycle, the phase where the ventricles actively push blood into the great vessels occurs after the ventricles have cleared the way by building enough pressure. Once ventricular pressure exceeds arterial pressure, the semilunar valves open and blood is ejected into the aorta and pulmonary trunk. This ventricular ejection phase is identified as the fourth phase in this phase sequence. After ejection, the ventricles begin to relax and the semilunar valves close, starting isovolumetric relaxation.
