The precise route over which pulse making impulse travels:
• Option “D” is correct i.e. S.A node-AV node-bundle of his-Purkinje fiber-heart muscles.
• The correct route through which pulse making impulse travels is S.A node-AV node-bundle of his-Purkinje fiber-heart muscles.
• The impulse travels through a path of fibers called the HIS-Purkinje network. This network directs the impulse into the ventricles and grounds them to contract. This powers blood out of the heart to the lungs and body.
