WebThe main purpose of the heart is to pump blood through the body; it does so in a repeating sequence called the cardiac cycle. The cardiac cycle is the coordination of the filling and emptying of the heart of blood by electrical signals that cause the heart muscles to contract and relax. The human heart beats over 100,000 times per day. WebFor the heart to work effectively, the atria and the ventricles must be activated rapidly and sequentially. Rapid activation is important in order to activate as much myocardium simultaneously as possible; the more …
