What term describes the structure that divides the right and left sides of the heart?

Explanation:
A septum is the wall that separates the right and left sides of the heart. There are specific septa for each pair of chambers: the atrial septum divides the atria, and the ventricular septum divides the ventricles. These walls keep the blood from mixing between the two sides, helping to maintain separate circulations for oxygen-poor and oxygen-rich blood. The cardiac skeleton, while essential for structure and conduction, is not the wall that divides the heart’s sides. So the term that describes the structure dividing the right and left sides is septum.
