The bundle of His and the Purkinje fibres are part of the conduction system of the heart. In order to pump blood around the body, the heart muscle must contract (atria first to fill the ventricles, then ventricles contract to send the blood around the body.) The conduction system starts in the sinoatrial node (SA node) which is also known as the hearts natural pacemaker and is located at the top of the right atrium. The impulse is then sent to the atrioventricular node (AV node) located by the junction between the atria and ventricles. The next part of the conduction system is the bundle of His which sends the impulse from the atria to the ventricles. The purkinje fibres then spread through the ventricles. As the impulse passes through each part of the conduction system, that part of the heart is excited and the heart muscle contracts, which gives the pumping action of the heart.
