What is the typical function of the Bundle of His in the conduction system of the heart?

• A. Generating impulses for atrial contraction
• B. Carrying impulses to ventricular foci
• C. Conducting impulses from the atria to the ventricles
• D. Regulating heart rate

Answer: (C)

The typical function of the Bundle of His, also known as the atrioventricular bundle, is conducting impulses from the atria to the ventricles. This structure is crucial in the heart's electrical conduction system, as it serves as a pathway for electrical signals to travel from the atrioventricular node (AV node) to the ventricles. Once the electrical impulses reach the Bundle of His, they can be further distributed through the right and left bundle branches, ultimately leading to coordinated ventricular contraction. This process ensures that the ventricles receive the necessary electrical signal to contract in sync after the atria have contracted, allowing for efficient blood flow through the heart and into the circulation.
