APPLIED RADIOLOGICAL ANATOMY

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 ventricular septum is a thick structure comprised of discrete muscular bands that separates the left and right ventricles, and contributes to cardiac function.

Detailed explanation-3: -The cardiac septum divides the heart into two halves, separating the right ventricle and right atrium from the left ventricle and left atrium. Blood which is poor in oxygen but rich in carbon dioxide flows into the right atrium and from there into the right ventricle.

Detailed explanation-4: -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.
