What is the partition between the right and left ventricles called?

• A. Interventricular septum
• B. Atrioventricular septum
• C. Interatrial septum
• D. Septal wall

Answer: (A)

The partition between the right and left ventricles is the interventricular septum. This thick muscular wall runs from the heart’s apex to its base, separating the two ventricular chambers and helping to keep oxygenated and deoxygenated blood apart. A small membranous portion near the base houses part of the conduction system. The term atrioventricular septum refers to the junction between the atria and ventricles and the valves there, while the interatrial septum separates the two atria. “Septal wall” isn’t a precise name for this structure. In clinical terms, a ventricular septal defect is a hole in the interventricular septum.
