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: -Structure of the Heart The heart has four chambers: two upper chambers call the right and left atrium and two lower chambers called the right and left ventricle. There is a wall between the two atria called the atrial septum. There is another wall between the two ventricles, and it is called the ventricular septum.

Detailed explanation-3: -septum (SEP-tum): The septum is a thick wall of muscle that divides the heart. It separates the left and right sides of the heart.

Detailed explanation-4: -A wall of muscle called the septum separates the left and right atria and the left and right ventricles. These are referred to as the atrial and ventricular septum.

Detailed explanation-5: -An important structure that separates the two ventricles is the interventricular septum. Anatomically it is divided into two parts: a thick, muscular part and a relatively thin membranous part. The muscular part of the interventricular septum separates most of the left and right ventricles from each other.
