How the Heart Works
Two hearts in one, working together in a continuous loop:
A pump on the right.
A pump on the left.
An electrical system keeps your heart beating in a normal rhythm.
The right side of the heart picks up the oxygen-poor blood from the body and moves it to the lungs for cleaning and re-oxygenating.
The left side of the heart moves the re-oxygenated blood throughout the body so that every part receives the oxygen it needs.
