Electric Heart Rythm

Your heart has electrical wiring, which keeps it beating. Electrical impulses begin high in the right atrium and travel through specialized pathways to the ventricles, delivering the signal to pump.
The conduction system keeps your heart beating in a coordinated and normal rhythm, which in turn keeps blood circulating. The continuous exchange of oxygen-rich blood with oxygen-poor blood is what keeps you alive.
The primary purpose for circulation is to provide fresh blood and nutrients to the rest of the body. The lungs are a vital part of the circulatory system as they are used to expel carbon dioxide a deadly toxin.
