Detailed explanation-1: -Muscular walls, called septa or septum, divide the heart into two sides. On the right side of the heart, the right atrium and ventricle work to pump oxygen-poor blood to the lungs. On the left side, the left atrium and ventricle combine to pump oxygenated blood to the body.

Detailed explanation-2: -The left and the right side of the heart is separated by a wall called septum. The partition between the chambers helps to avoid the mixing up of blood rich in oxygen with blood rich in carbon dioxide.

Detailed explanation-3: -…a partition known as the interatrial septum; the lower chambers, the ventricles, are separated by the interventricular septum.
