Final answer:
Both parts of the statement are true: the AV node does deliver the stimulus to the AV bundle, and the AV bundle is indeed located within the interventricular septum.
Step-by-step explanation:
The statement "The AV node delivers the stimulus to the AV bundle, located within the interventricular septum" is asking us to determine the accuracy of two parts: whether the atrioventricular (AV) node delivers the stimulus, and whether the atrioventricular bundle is located within the interventricular septum.
The first part of the statement is true, as the AV node indeed receives the electrical impulse from the sinoatrial (SA) node and then delivers it to the AV bundle after a critical pause. This pause allows the atria to complete their contraction and pump blood into the ventricles. The second part of the statement is also true. Arising from the AV node, the AV bundle, or bundle of His, extends into the interventricular septum before dividing into the right and left bundle branches that supply the corresponding ventricles.
Therefore, the correct answer is C) Both parts of the statement are true.
