Valves
fold or duplication of the endocardium
- two atrioventricular (AV) valves - between the atria and the ventricles, are the mitral valve and the tricuspid valve.
- formed by a fold or duplication of the endocardium with a dense connective tissue core
- upper or atrial surface of the valve is thick and resembles atrial endocardium, and the lower or ventricular surface of the valve is thin and resembles ventricular endocardium.
- two semilunar (SL) valves - in the arteries leaving the heart, are the aortic valve and the pulmonary valve (pulmonary artery (trunk) and the aorta)
- endothelium on the cardiac side is squamous. Elastic fibres
