What event occurs when electrical impulses from the atrioventricular node are transmitted to the entire ventricular system? The Bundle of His and the Purkinje fibers transmit the electrical impulses from the atrioventricular node to the entire ventricular system, resulting in or contraction from the bottom of the heart.

Conduction of impulses between the atria and the ventricles is channelled through the a. Annulus fibrosus b. AV node c. SA node d. Bundle of His

The AV node releases an electrical impulse to cause the contraction of which chambers of the heart?ventriclesatria

Choose all the functions of the atrioventricular node.Question 1Select one or more:a.causes all the tissue of the ventricles to contract almost at once. b.to regulate ventricular systole.c.sends out rapid impulses throughout the ventricular tissue, causing the cells to contract.d.Receives impulses from the sinoatrial node.

The atrioventricular node a. Is connected to specialized wide, fast conducting myocytes in the bundle of His and Purkinje fibres b. Delays impulses for about 200 ms, allowing time for atrial contraction to complete ventricular filling c. Is a band of fibrous connective tissue which separates the atria from the ventricles d. Conducts impulses rapidly allowing almost immediate activation of ventricular muscle

The part of the cardiac conduction system that excites contraction of the interventricular septum is the ________________.
