The endocardium (inner layer; tunica intima) lines the heart cavity, is in contact with the flowing blood, smoothly passes into the tunic of the vascular intima, forms the heart valves. It consists of 4 layers:

  1. endothelium (endothelial cells);
  2. subendothelium (collagen ligament);
  3. elastic-muscular layer (collagen and elastic ligament, smooth muscle cells; this layer is especially strong in the atria);
  4. subendocardium (a sparse connective tissue found here in the structure of the cardiac conduction system).
