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 cardiac septum divides the heart into two halves, separating the right ventricle and right atrium from the left ventricle and left atrium. Blood which is poor in oxygen but rich in carbon dioxide flows into the right atrium and from there into the right ventricle.

Detailed explanation-3: -The interventricular septum, also known as the ventricular septum, refers to the triangular wall of cardiac tissue that separates the left and right ventricles (i.e., the lower chambers) of the heart.

Detailed explanation-4: -It forms a barrier in the four-chamber of heart. It prevents oxygenated and deoxygenated blood from mixing. In the absence of septum double circulation has not occurred properly.
