Which part of the cardiac conduction system receives the impulse from the SA node?
A) SA node
B) AV node
C) Bundle of His
D) Purkinje fibers
E) Bundle branches
SA Node
The sinoatrial node, a group of cells in the right atrium of the heart that acts as a natural pacemaker, initiating the heart's electrical impulses.
AV Node
The AV Node, or Atrioventricular Node, is a part of the heart's electrical system that acts as a gatekeeper, controlling the electrical impulses between the atria and ventricles.
Cardiac Conduction
The process by which the heart's electrical system transmits signals, leading to muscle contraction and heartbeats.
