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. WebApr 10, 2024 · The cycle begins when the two atria contract, which pushes blood into the ventricles. Then, the ventricles contract, which forces the blood out of the heart.
