Anatomical terminology

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

The ventricular septum is directed obliquely backward to the right, and curved with the convexity toward the right ventricle; its margins correspond with the anterior and posterior longitudinal sulci.
