Explanation:
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 right and left sides of the heart are separated by a muscular wall that prevents blood without oxygen from mixing with blood that has oxygen. The heart also has valves that separate the chambers and connect to major blood vessels.
