THORAX ABDOMEN AND PELVIS

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: -Separation of left and right ventricular chambers is dependent on a single structure, the interventricular septum (IVS), which has both muscular and mesenchymal components. Little is known about the morphogenetic events that lead to the formation of the muscular component of the IVS.

Detailed explanation-3: -The cardiac septum divides the heart into two halves, separating the right ventricle and right atrium from the left ventricle and left atrium. Blood which is poor in oxygen but rich in carbon dioxide flows into the right atrium and from there into the right ventricle.

Detailed explanation-4: -The interventricular septum (IVS, or ventricular septum, or during development septum inferius) is the stout wall separating the ventricles, the lower chambers of the heart, from one another.
