The interventricular septum separates the right and left ventricles. The interatrial septum separates the atria.
The interatrial septum separates the left and right atria.
The interatrial septum separates the right and left atria. This wall prevents the mixing of oxygen-rich and oxygen-poor blood.
septum
The thinnest portion of the wall between the two atria is the interatrial septum, which separates the right and left atria of the heart. This wall is thin and marked by a depression called the fossa ovalis, which is a remnant of the fetal foramen ovale.
The intraventricular septum separates the right ventricle from the left ventricle.
the septum
If you mean the heart, the atria are separated from each other by the atrial septum. If you mean the atria from the ventricles, the right is separated by an AV valve called the tricuspid. The left by a an AV valve called the bicuspid or mitral valve.

Septum
The muscular wall that separates the heart into right and left sides is called the septum. It prevents mixing of oxygenated and deoxygenated blood in the heart chambers. The septum ensures efficient circulation by maintaining separate pathways for blood to flow to the lungs and the rest of the body.
The septum, or septal wall as it is often referred to, is what separates the left and right ventricles.
