Where is the right and left bundle branches located?

The right and left bundle branches are part of the heart's conduction system and are located in the interventricular septum, which separates the left and right ventricles. The right bundle branch runs along the right side of this septum, while the left bundle branch extends into the left ventricle and further divides into anterior and posterior fascicles. Both branches transmit electrical impulses from the atrioventricular (AV) node to the ventricles, facilitating coordinated contraction of the heart muscle.
