The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes. The vital importance of the heart is obvious. If one assumes an average rate of contraction of 75 contractions per minute, a human heart would contract approximately 108, 000 times in one day, more than 39 million times in one year, and nearly 3 billion times during a 75year lifespan. The conduction system includes several components. The first part of the conduction system is the [glossary term: sinoatrial node. Without any neural stimulation, the sinoatrial node rhythmically initiates impulses 70 to 80 times per minute. The atrioventricular valves connect an atrium and a ventricle: between the right atrium and right ventricle is the tricuspid valve and between the left atrium and left ventricle is the mitral valve. The semilunar valves are valves at the blood's exit points from the heart: the pulmonary valve opens from the right ventricle into the pulmonary artery, and the aortic valve.
