A) the sinoatrial (SV) node

Question

Quizplus · Accepted Answer

Purkinje fibers are specialized conductive fibers located within the walls of the heart's ventricles. They are responsible for carrying the electrical signals from the atrioventricular (AV) node to the ventricles, ensuring that the ventricles contract in a coordinated manner after the atria, facilitating efficient blood flow through the heart.
