PATHOLOGY

Detailed explanation-1: -The interventricular septum separates the ventricles and allows for proper blood flow through the heart: from the right atrium through the tricuspid valve to the right ventricle to the lungs, back to the left atrium, followed by the left ventricle through the mitral valve.

Detailed explanation-2: -The interventricular septum (IVS) accommodates the ventricular portion of the conduction system and contributes to the mechanical function of both ventricles.

Detailed explanation-3: -The ventricular septum is a thick structure comprised of discrete muscular bands that separates the left and right ventricles, and contributes to cardiac function.
