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 heart’s septum is a wall separating the right and left sides of the heart. The heart has two upper chambers called atria and two lower chambers called ventricles. The heart’s septum comprises the atrial septum, which separates the atria, and the ventricular septum, which separates the ventricles.
