The molecular architecture of the heart`s conduction system in health
... The cardiac conduction system (CCS) acts as the heart’s wiring system and is vital for the initiation and coordination of the heart beat (Boyett, 2009). The main tissues comprising the CCS are the sinoatrial node (the pacemaker of the heart), atrioventricular node (responsible for slow action potent ...

... The heart is the key organ in the circulatory system. As a hollow, muscular pump, its main function is to propel blood throughout the body. It usually beats from 60 to 100 times per minute, but can go much faster when necessary. It beats about 100,000 times a day, more than 30 million times per year ...
