Internal Structure And Conduction System Of The Heart

Internal Structure And Conduction System Of The Heart — a labelled NEET Biology diagram with a definitions lexicon.

Internal Structure and Conduction System of the Heart Labelled parts: SA Node, AV Node, Right Atrium, Left Atrium, Right Ventricle, Left Ventricle, Tricuspid Valve, Bicuspid Valve, Mitral Valve, Pulmonary Valve, Aortic Valve, Purkinje Fibers. The sinoatrial node, known as the natural pacemaker, initiates the heart's electrical impulse. The atrioventricular node, which delays the electrical impulse before passing it to the ventricles. Specialized fibers that conduct electrical impulses through the ventricular walls causing contraction.
