Where is the AV bundle located?

The AV bundle, also known as the bundle of His, is located on the wall between the right atrium and the right ventricle. This structure plays a crucial role in the conduction system of the heart, as it carries electrical impulses from the atria to the ventricles, ensuring coordinated contraction of the heart chambers.

The position of the AV bundle is significant because it connects the atrial conduction pathways (atria) to the ventricular conduction pathways, allowing the electrical signals to travel efficiently and maintain a synchronized heartbeat. This critical transition from atrial to ventricular contraction is essential for effective cardiovascular function.

Understanding the anatomy and location of the AV bundle helps in comprehending how electrical signals are propagated through the heart, and it is fundamental knowledge for interpreting EKGs and diagnosing cardiac conditions. The other locations mentioned do not accurately reflect the AV bundle's positioning or role in the heart's conduction system.
