Final answer:

The Purkinje fibers in the cardiac conduction system are responsible for causing the ventricles of the heart to contract. This is part of the electrical impulse sequence that begins with the SA node and passes through the AV node and bundle branches before reaching the Purkinje fibers.The correct option is C

Step-by-step explanation:

The part of the cardiac conduction system that is located in the wall of the ventricle and causes the ventricles to contract is the Purkinje fibers. The cardiac conduction system is responsible for initiating and propagating the electrical impulses that result in heart contraction

The sequence starts with the sinoatrial (SA) node generating an impulse that travels through the atria, causing them to contract. It then pauses at the atrioventricular (AV) node before it travels down the bundle of His and into the bundle branches.

These branches extend through the interventricular septum before reaching the Purkinje fibers. It is when the impulse reaches the Purkinje fibers that the ventricles contract, completing the process of sending blood out of the heart.The correct option is C.
