septum
Pump blood directly to the atria.
The structure of the conduction system formerly known as the bundle of His is now referred to as the atrioventricular (AV) bundle. It is responsible for conducting electrical impulses from the atria to the ventricles of the heart. The AV bundle splits into right and left bundle branches that extend into the ventricles, facilitating coordinated contraction.
