Which of the following statements is true about the phases of the cardiac cycle? During atrial systole, the semilunar valves are open. During ventricular ejection, the semilunar valves are closed. When aortic pressure is higher than the ventricular pressure, the semilunar valves open. When atrial pressure is higher than the ventricular pressure the AV valves are open. During isovolumetric contraction, all of the valves are open.
