in this class, I learned that the phases of the cardiac cycle are: 1. Ventricular filling, this occurs when the heart chambers relax and blood goes from right atrium to right ventricle via tricuspid valve. 2. Ventricular systole, as the ventricles contract, intraventricular pressure rises, closing the av valves. blood is ejected from the heart through pulmonary trunk to the lungs and aorta.
