This wall separates the ventricles, which are the lower two heart chambers and the major pumping chambers of the heart. It is important that full separation is achieved and each ventricle functions without any type of blood communication with the other.
interventricular septum
A septum connects both upper and lower chambers of the heart. This one is the ventricular septum.
Interventricular septum
septum
In the interventricular septum lies the hindle of His (pronounced hiss) and the bundle branches. These structures carry the impulses from the AV node down to the purkinje fibres.
anterior interventricular sulcus
It is called the interventricular septum.
the diaphragm
interventricular septum
Anterior and Posterior Interventricular Sulcus. Sulcus meaning "groove" .
The interventricular septum is the wall that separates the lower chambers of the heart from one another. These chambers are referred as the right and left ventricles.
The interatrial septum is composed of a thin layer of connective tissue, while the interventricular septum is thicker and contains muscle tissue. The interventricular septum also has specialized conducting tissue that helps coordinate the contraction of the heart muscle.
