Question

What is Chondrae tendineae ? What is its structure and function?

Answer 1

The chordae tendineae (tendinous chords), colloquially known as the heart strings, are cord-like tendons that connect the papillary muscles to the tricuspid valve and the bicuspid valve in the heart. Chordae tendineae are approximately 80% collagen, while the remaining 20% is made up of elastin and endothelial cells.
Function: chordae tendineae play a vital role in holding the atrioventricular valves in place while the heart is pumping blood.
