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: -On the right side of the heart, the right atrium and right ventricle work to pump oxygen-poor blood returning from the body back to the lungs to be reoxygenated. On the left side of the heart, the left atrium and left ventricle combine to pump oxygenated blood back through the body.

Detailed explanation-3: -The interatrial septum is a thin wall of tissue that separates the two upper chambers of the heart, called the right and left atria.

Detailed explanation-4: -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-5: -Your heart has four separate chambers that pump blood. The chambers are called the right atrium, right ventricle, left atrium, and left ventricle. 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.
