Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	True
B	False
C	Either A or B
D	None of the above

Explanation:

Detailed explanation-1: -Cardiac cycle events can be divided into diastole and systole. Diastole represents ventricular filling, and systole represents ventricular contraction/ejection. Systole and diastole occur in both the right and left heart, though with very different pressures (see hemodynamics below).

Detailed explanation-2: -During ventricular systole the ventricles are contracting and vigorously pulsing (or ejecting) two separated blood supplies from the heart-one to the lungs and one to all other body organs and systems-while the two atria are relaxed (atrial diastole).
