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 contraction of ventricle is referred as systole. The stroke volume is also called as the blood which is ejected out from the ventricle when the left ventricle contracts for one time.
Detailed explanation-3: -The atria begin to contract (atrial systole), following depolarization of the atria, and pump blood into the ventricles. The ventricles begin to contract (ventricular systole), raising pressure within the ventricles.
