ANATOMY

Detailed explanation-1: -There is an atrial septum that separates the right and left atriums and a ventricular septum that separates the right and left ventricles.

Detailed explanation-2: -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-3: -Muscular walls, called septa or septum, divide the heart into two sides.

Detailed explanation-4: -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.

Detailed explanation-5: -The atrioventricular septum is the middle portion of the cardiac wall that divides the heart into left and right sides. This division takes place over just 10 days in the 4th and 5th week of an embryo’s development. Its job is to prevent mixing of oxygenated and unoxygenated blood.
