Events of the Cardiac Cycle Why did the blood flow across the valve? Desire - it wanted to Ability - it could do it Movement = Desire X Ability Flow.
The cardiac cycle Ventricular filling the diastole refers to the period of the cardiac cycle during which the ventricles are filling with blood the systole.
