Detailed explanation-1: -Cardiac cycle events can be divided into diastole and systole. Diastole represents ventricular filling, and systole represents ventricular contraction/ejection.
Detailed explanation-2: -Systole represents the time during which the left and right ventricles contract and eject blood into the aorta and pulmonary artery, respectively. During systole, the aortic and pulmonic valves open to permit ejection into the aorta and pulmonary artery.
Detailed explanation-3: -Systolic Function. Systole is best described as the period that starts when the heart is maximally filled with blood and then subsequently ejected from the ventricle to the aorta whereupon the aortic valve closes. The volume of blood ejected from the heart is the stroke volume (SV).
