Hint: Inter ventricular septum (IVS, or ventricular septum, or during development septum inferius) is the stout wall separating the ventricles, the lower chambers of the guts , from each other.

Complete answer:
The inter ventricular septum is found within the heart of birds and mammals because they need a 4-chambered heart, that is, 2 atria and a couple of ventricles. This is often where the separation of oxygenated and deoxygenated blood takes place. The interventricular septum is the separation wall between these two.

The main function of the interventricular septum is that it contributes to the pumping function of the ventricle. The inter ventricular septum is the stout wall separating the ventricles, the lower chambers of the guts, from each other.

The ventricular septum is directed obliquely backward to the proper, and curved with the convexity toward the proper ventricle; its margins correspond with the anterior and posterior longitudinal sulci. The greater portion is thick and muscular and constitutes the muscular inter ventricular septum.

Its upper and posterior part, which separates the aortic vestibule from the lower part of "> a part of the proper atrium and upper part of the proper ventricle, is thin and fibrous, and is termed the membranous ventricular septum.

Note: The posterior inter ventricular artery, a branch of right arteria coronaria , supplies the posterior 1/3 of the inter ventricular septum. The remaining anterior 2/3 is supplied by the anterior inter ventricular artery which may be a septal branch of the left anterior descending artery, which may be a branch of left arteria coronaria .
