The wall of the heart consists of three layers of tissue:Epicardium — protective layer mostly made of connective tissue.Myocardium — the muscles of the heart.Endocardium — lines the inside of the heart and protects the valves and chambers....
The right ventricle is entered via the tricuspid valve whose 3 cusps are held by papillary muscles and chordae tendineae. The right ventricular wall shows trabeculae carneae and contains the septomarginal trabecula which carries conducting tissue. Blood leaves this chamber via the pulmonary valve. ...
