The conduction system is responsible for generating and coordinating the electrical signals that cause the heart to contract. It includes the sinoatrial node which initiates electrical impulses, the atrioventricular node which receives impulses and delays transmission to the ventricles, and the Bundle of His and Purkinje fibers which rapidly conduct electrical signals to contract the ventricles.
