Where is the location of the atrioventricular bundle?branches between left and right ventriclesbranches between left and right atrium

The atrioventricular (AV) bundle, also known as the bundle of His, is located in the heart. Here are the steps to locate it:

1. Start at the heart: The heart is located in the chest, slightly to the left of the sternum (breastbone) and between the lungs.

2. Identify the atria: The heart has four chambers. The two upper chambers are called the left and right atria.

3. Locate the atrioventricular node: This is located at the bottom of the right atrium. The AV node is a cluster of cells that helps regulate heart rate.

4. Find the atrioventricular bundle: The AV bundle begins at the AV node. It extends from the AV node into the fibrous skeleton of the heart, between the atria and the ventricles.

5. Trace the path of the AV bundle: The AV bundle travels along the interventricular septum, the wall that separates the left and right ventricles. It then divides into two branches, the left bundle branch and the right bundle branch. These branches carry electrical signals to the left and right ventricles, respectively.

So, the atrioventricular bundle is located in the heart, starting at the AV node at the bottom of the right atrium and extending down the interventricular septum to the left and right ventricles.
