Interventricular septum

This section is about
Structures of the Heart

The interventricular septum is a part of the structure (anatomy) of the heart and separates the left ventricle from the right ventricle.

This septum between the two ventricles is thickest at the lowest part of its structure. The upper part of the interventricular septum is called the membranous part of the septum. As it raises upwards within the heart it tapers off to becomes a mass of muscular fibres consisting of fibrous tissue covered by two layers of endocardium.


(In the same way as the interventricular septum separates the right- and left- ventricles, the interatrial septum separates the left atrium from the right atrium within the structure of the heart.)
