Essentially it is a muscle which functions as a really powerful pump. How the Heart works: Step by Step Functions with diagrams. Your heart has its own electrical system that coordinates the work of the heart chambers (heart rhythm) and also controls the frequency of beats (heart rate). In such a system, a continuous flow of the same liquid can be pumped through the loop again and again. Step two is that blood enters into the right atrium.

It is a closed system, meaning blood does not enter or leave the system during its journey from your heart to your body and back again.
