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 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-3: -The septum separates the atria and ventricles in such a way that it forms a barrier between the heart chambers and this prevents mixing of oxygenated and deoxygenated blood.

Detailed explanation-4: -Where as ventricles have to pump blood to lungs from right side and to the whole body on the left side. So ventricles have to work with greater strength to pump blood to far off places. That is the reason why ventricles have more muscular walls.To pump with more force the muscles of the ventricles are thicker.
