The electrical part of the heart

The body has electrical currents.

It then moves from the pulmonary valve, into the pulmonary artery to the lungs.

After picking up oxgen into the lungs, the blood moves out of the lungs into the pulmonary veins, into the left atrium, through the mitral valve, and into the left ventricule that pushes blood to the body through the aortic valve.
