Which of the following is NOT part of the conducting system of the heart?

A) bundle of His
B) AV node
C) SA node
D) AV valve

Conducting System

A network of specialized cardiac muscle cells responsible for initiating and distributing the electrical impulses that stimulate heart contraction.

AV Valve

The atrioventricular (AV) valve regulates blood flow from the atria to the ventricles in the heart.

Bundle of His

A collection of heart muscle cells specialized for electrical conduction that transmits the electrical impulses from the AV node to the point of the apex of the fascicular branches.

Final Answer :
D
Explanation :
The AV valve, also known as the atrioventricular valve, is not part of the conducting system of the heart. It is a type of heart valve that controls blood flow between the atria and the ventricles. The other three options (bundle of His, AV node, and SA node) are all structures that make up the conducting system of the heart, which is responsible for coordinating the electrical impulses that regulate heart rate and rhythm.
