What is the term for the divider between the heart chamber walls?

The term for the divider between the heart chamber walls is known as the septum. The septum plays a crucial role in separating the different chambers of the heart, specifically the right and left atria as well as the right and left ventricles. This separation is essential for proper blood flow through the heart and prevents the mixing of oxygenated and deoxygenated blood.

The septum is composed of muscular tissue and is vital for maintaining the efficiency of heart function and overall cardiovascular health. Understanding the structure and function of the septum is fundamental for those studying cardiology and related medical fields, as it has direct implications on various heart conditions and their treatments.

The other terms listed refer to different structures associated with the heart: valvula pertains to valve structures in the heart, aorta is the major artery that carries blood away from the heart, and myocardium refers to the muscle tissue of the heart itself. Each of these components plays important roles in the overall function of the heart, but only the septum specifically denotes the divider between the heart chamber walls.
