What structure does the Bundle of His conduct impulses to?

• A. The sinoatrial node
• B. The ventricles
• C. The aorta
• D. The coronary arteries

Answer: (B)

The Bundle of His, also known as the atrioventricular bundle, plays a crucial role in the cardiac conduction system. It is responsible for transmitting electrical impulses from the atrioventricular node to the ventricles. This transfer of impulses allows for the coordinated contraction of the ventricles, ensuring that blood is effectively pumped out of the heart. When the Bundle of His conducts impulses, it branches into the right and left bundle branches, which run along the interventricular septum and eventually lead to Purkinje fibers. This system ensures that the ventricles contract after a brief delay, allowing the atria to fully empty their blood into the ventricles. Therefore, understanding the function and pathway of the Bundle of His is essential for grasping how the heart maintains its rhythm and coordination during the cardiac cycle.
