AV bundle/Bundle of HIS is located in

Options

A. atrioventricular septum
B. inter atrial septum
C. interventricular septum
D. the walls of right atrium

Answer

To determine the location of the AV bundle, also known as the Bundle of His, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the AV Bundle**: The AV bundle, or Bundle of His, is a crucial part of the heart's electrical conduction system. It transmits impulses from the atrioventricular (AV) node to the ventricles.

2. **Identifying the Location Options**: The question provides four options regarding the location of the AV bundle:
- A) Atrioventricular septum
- B) Inner atrial septum
- C) Inner ventricular septum
- D) Right atrium

3. **Analyzing the Options**:
- **Atrioventricular septum**: This is the wall that separates the atria from the ventricles and is where the AV bundle is located.
- **Inner atrial septum**: This is the wall that separates the left and right atria, not where the AV bundle is found.
- **Inner ventricular septum**: This is the wall that separates the left and right ventricles, not the location of the AV bundle.
- **Right atrium**: The AV bundle is not located in the right atrium.

4. **Conclusion**: Based on the analysis, the AV bundle is located in the atrioventricular septum. Therefore, the correct answer is **A) Atrioventricular septum**.

### Final Answer:
The AV bundle (Bundle of His) is located in the **atrioventricular septum**.
