Which of the Following is the Correct Conduction Pathway Through

Question

Which of the following is the correct conduction pathway through the heart?
A) SA node, Purkinje fibers, AV node, bundle of His, bundle branches
B) SA node, AV node, bundle of His, bundle branches, Purkinje fibers
C) AV node, SA node, bundle branches, bundle of His, Purkinje fibers
D) Purkinje fibers, bundle of His, bundle branches, SA node, AV node
E) Bundle of His, bundle branches, Purkinje fibers, SA node, AV node

Accepted Answer

The correct conduction pathway through the heart starts at the sinoatrial (SA) node, moves to the atrioventricular (AV) node, then through the bundle of His, into the bundle branches, and finally through the Purkinje fibers. This pathway ensures the coordinated contraction of the heart chambers.
