Between the first and second heart sounds of the cardiac cycle, there is a period of contraction of the ventricles of the heart called systole (the sequence of events in a single heart beat).
Blood is ejected into the aorta and pulmonary trunk during systole. “Oxygenated blood is pumped into the aorta, and deoxygenated blood is pumped into the pulmonary artery,” is the right answer.
Final Answer : Option D : During ventricular systole Oxygenated blood is pumped into the aorta and deoxygenated blood is pumped into the pulmonary artery.
