WebAt the start of atrial systole, the ventricles are normally filled with approximately 70–80 percent of their capacity due to inflow during diastole. Atrial contraction, also referred to as the “atrial kick,” contributes the … WebDuring ventricular diastole, venous blood enters the left atrium, and when blood pressure within the left atrium exceeds blood pressure in the left ventricle, the mitral valve opens and passive filling of the ventricle occurs. This continues until this cardiac cycle ends, and atrial systole marks the beginning of the next cycle.
