Question

what is the significance of atrio ventricular node and atrio ventricular bundle
​

Answer 1

Explanation:

• The atrioventricular (AV) node is present in the right atrium, near the base of the inter- auricular septum that separates the right auricle from the ventricle. It gives rise to the bundle of His that conducts the cardiac impulses from the auricles to the ventricles.

Answer 2

Atrio ventricular node:

The atrioventricular node or AV node is a part of the electrical conduction system of the heart that coordinates the top of the heart. It electrically connects the atria and ventricles.

Atrio ventricular bundle :

​The atrioventricular bundle is the extension of the atrioventricular node from the atrium across the fibrous skeleton of the heart to the ventricles. It passes from the anterior and inferior part of the AVN as a group of specialised myocytes within an insulating sheath of connective tissue.
