Detailed explanation-1: -The interventricular septum, also known as the ventricular septum, refers to the triangular wall of cardiac tissue that separates the left and right ventricles (i.e., the lower chambers) of the heart. The entire interventricular septum can be further divided into two parts: a muscular portion and a membranous portion.

Detailed explanation-2: -A wall of muscle called the septum separates the left and right atria and the left and right ventricles. These are referred to as the atrial and ventricular septum.

Detailed explanation-3: -The interventricular septum is a triangular wall of cardiac tissue that comprises muscular and membranous tissue. The muscular portion consists of the inlet septum, trabecular septum, and infundibular septum. It receives blood from the left coronary artery.

Detailed explanation-4: -The interatrial septum is the wall of tissue that separates the right and left atria of the heart.
