Understand the cardiac cycle phases: The cardiac cycle consists of several phases, including atrial systole, ventricular systole, and ventricular diastole.
Identify ventricular systole: During ventricular systole, the ventricles contract, increasing the pressure inside them.
Recognize the role of pressure: As the pressure in the ventricles exceeds the pressure in the pulmonary trunk and aorta, the semilunar valves open.
Determine blood flow direction: The opening of the semilunar valves allows blood to flow from the ventricles into the pulmonary trunk and aorta.
Conclude the phase: Therefore, the phase of the cardiac cycle when blood flows from the ventricles into the pulmonary trunk and aorta is ventricular systole.
