During a cardiac cycle, the ventricular systole will lead to:
| 1. | ventricular filling. |
| 2. | the atrioventricular valves to close, and then the semilunar valves to open. |
| 3. | the semilunar valves to close, and then the atrioventricular valves to open. |
| 4. | pressure to become greater in the aorta and pulmonary trunk than in the ventricles. |
