The atria and ventricles work together, alternately contracting and relaxing to pump blood through your heart. ... The electrical activity spreads through the walls of the atria and causes them to contract. This forces blood into the ventricles. The SA node sets the rate and rhythm of your heartbeat.

The blood pumps oxygenated blood to parts of the body and pumps deoxygenated blood to the lungs.
The blood flows through 4 Chambers of the Heart.
This results in Heart's contraction and relaxation.
Therefore,
Heart starts beating and Heart beat is created.
Hope this will help you.
