Let's examine the anatomy of the heart along with some diagrams that show how the heart operates. Human chordae tendineae originating from the left ventricles were obtained from 7 embalmed cadavers and 6 postmortem subjects of various ages. Labeled pictures of the human heart.
Chordae tendineae are approximately 80% collagen, while the remaining 20% is made up of elastin and endothelial cells.
Observations were made by illuminating the chordae along their axes. The chordae tendineae and the papillary muscles from which they arise limit the extent to which the portions of… …cords of dense tissue (chordae tendineae) covered by thin endocardium extend from the nipplelike papillary muscles to connect with the ventricular surface of the middle supporting layer. The heart is a muscular organ located in the middle mediastinum that pumps blood through the circulatory system. Degenerative cardiac disorders often cause the heart strings to rupture.
