What Is The Conduction System Of The Heart
Olivia Luz
The cardiac conduction system is a network of specialized cardiac muscle cells that initiate and transmit the electrical impulses responsible for the coordinated contractions of each cardiac cycle.
The conduction system of the heart controls its pumping action which results in the delivery of blood to the different organs and tissues of the body. The sinus node is the heart s natural pacemaker. The cardiac conduction system involves the spread of electrical activity from the sinoatrial node to the atrioventricular node down the bundle of his and along the purkinje fibres. The constant cycle of heart muscle contraction followed by relaxation causes blood to be pumped throughout the body.
The cardiac conduction system is a collection of nodes and specialised conduction cells that initiate and co ordinate contraction of the heart muscle. The conduction system consists of pacemaker cells that generate spontaneous action potentials and then deliver those impulses throughout the heart. Conduction system of the heart. This conduction system is composed of a group of special cells found in the walls of the heart muscle which send the electrical impulses and cause the heart muscle to contract.
In order of normal conduction the system consists of the sinoatrial node the intra atrial tracts the atrioventricular node the bundle of his the right and left bundle branches and the purkinje fibers. The electrical conduction system of the heart transmits signals generated usually by the sinoatrial node to cause contraction of the heart muscle. The conducting system of the heart consists of cardiac muscle cells and conducting fibers not nervous tissue that are specialized for initiating impulses and conducting them rapidly through the. Cardiac conduction is the rate at which the heart conducts electrical impulses.

These impulses cause the heart to contract and then relax. The pacemaking signal generated in the sinoatrial node travels through the right atrium to the atrioventricular node along the bundle of his and through bundle branches to cause contraction of the heart muscle. This system generates electrical impulses and conducts them throughout the muscle of the heart stimulating the heart to contract and pump blood.
