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: -Systole is the phase when the heart contracts. During this phase, it squeezes out blood to the rest of the body. Diastole is the phase when the heart relaxes. During this phase, it fills up with blood to prepare for its next beat.
