===== [[Summary Article|'''SUMMARY''']] =====
1. RA systole precedes LA systole.
<br/>
<br/>2. LV contracts before RV.
<br/>
<br/>3. RV ejection begins before LV ejection (since PA pressure is lower than aortic pressure).
<br/>
<br/>4. During inspiration, the aortic valve closes slight before pulmonic valve.
<br/>
<br/>5. During expiration, the pulmonary &amp; aortic valves close at the same time.
