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: -Your heart has a right and left side separated by a wall called the septum. On each side of the wall, there is a small collecting chamber called an ‘atrium’, which leads into a large pumping chamber called a ‘ventricle’.
Detailed explanation-3: -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.
