Definitions:

AV Bundle

The 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.

Bundle Branches

Pathways in the heart's electrical conduction system that transmit impulses from the AV node to the ventricles, ensuring coordinated heartbeats.

Interventricular Septum

The thick wall separating the lower chambers (ventricles) of the heart, which prevents the mixing of oxygenated and deoxygenated blood.

Mitral Valve

A valve in the heart situated between the left atrium and left ventricle that prevents the backflow of blood into the atrium.
