ANATOMY

Detailed explanation-1: -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-2: -The interventricular septum is the wall of cardiac muscle and membranous tissue that separates the left and right ventricles.

Detailed explanation-3: -The heart’s septum is a wall separating the right and left sides of the heart. The heart has two upper chambers called atria and two lower chambers called ventricles. The heart’s septum comprises the atrial septum, which separates the atria, and the ventricular septum, which separates the ventricles.

Detailed explanation-4: -A ventricular septal defect (pronounced ven·tric·u·lar sep·tal de·fect) (VSD) is a birth defect of the heart in which there is a hole in the wall (septum) that separates the two lower chambers (ventricles) of the heart. This wall also is called the ventricular septum.
