MICROANATOMY

Detailed explanation-1: -The septum separates the right and the left side of the heart in such a way that it forms a barrier between the heart chambers and this prevents the mixing of oxygenated and deoxygenated blood.

Detailed explanation-2: -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-3: -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.
