The conduction of impulses between the atria and the ventricles is channeled through the AV node.

Here's a step-by-step explanation:

1. The process begins in the Sinoatrial (SA) node, also known as the heart's natural pacemaker. This node sends an electrical signal that causes the atria, the upper chambers of the heart, to contract.

2. The signal then arrives at the Atrioventricular (AV) node, which is the answer to your question. The AV node serves as a kind of relay station. It slows down the electrical signal before sending it to the ventricles, the lower chambers of the heart. This delay ensures that the atria have enough time to fully contract before the ventricles do.

3. From the AV node, the signal travels along the Bundle of His. This bundle splits into two branches that carry the signal to the left and right ventricles.

4. Finally, the signal reaches the Purkinje fibers, which distribute it throughout the ventricles, causing them to contract and pump blood either to the lungs or to the rest of the body.

So, the correct answer is b. AV node.
