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.

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: -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.

Detailed explanation-4: -The atrio-ventricular septum separates the right atrium from the base of the left ventricle outflow tract.

Detailed explanation-5: -The ventricular septum is a thick structure comprised of discrete muscular bands that separates the left and right ventricles, and contributes to cardiac function.
