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: -The cardiac cycle is essentially split into two phases, systole (the contraction phase) and diastole (the relaxation phase).
Detailed explanation-3: -The contraction phase is called systole and relaxation phase is called diastole.
