Which one of the following statements is correct?
| 1. | Increased ventricular pressure causes closing of the semilunar valves. |
| 2. | The atrio-ventricular node (AVN) generates an action potential to stimulate atrial contraction. |
| 3. | The tricuspid and the bicuspid valves open due to the pressure exerted by the simultaneous contraction of the atria. |
| 4. | Blood moves freely from atrium to the ventricle during joint diastole. |
