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
  • dense fibrous connective tissue core (with some loose connective tissue also evident) and endothelium on either side.
