My problem is how does the heart beat pump blood and receive blood all at the same time

My reaserch covers Cardiac Conduction System ,CadioVascular System , the 5 main diseases, and the summary of how to keep your heart heathy in my logbook.

Our heart has a special electrical system called the cardiac conduction system; It is an electrical system that controles the heart rate and its rhythm.

Each heart beat has an electrical signal that travels from the top of the heart to the bottom. The signal makes the heart contractions and pumping the blood around all of the body through blood vessels.

The heart uses blood vessels (arterys and veins) to pump the blood.The heart uses Artery's and Arterioles and capillaries to get blood around your body (oxgenated blood).The heart also uses Veins and Ventioles and capillaries that take deoxegenated blood back to your heart.For your heart to beat an electrical signal travels to your heart that tells your heart to contract so when it uncontracts blood goes through your blood vessels.
