Your heart doesn’t just pump blood—it beats thanks to a specialized electrical system that ensures a steady rhythm. The conduction system starts in the sinoatrial (SA) node, also known as the heart’s natural pacemaker, sending impulses through the atria. These signals then travel to the atrioventricular (AV) node and down through the bundle of His and Purkinje fibers, which make the ventricles contract. This synchronized rhythm keeps blood flowing smoothly throughout the body. #HeartAnatomy #ConductionSystem #Cardiology #HeartHealth
