The chordae tendineae of the av valves are anchored to the Papillary muscle of the ventricle of the ventricles.
Chordae tendinae are code like tendons that connect the papillary muscles to the tricuspid valve and the mitral valve. (atrioventricular valves). This papillary muscle are located in the ventricle of the heart and they attach to the cusps of atrioventricular valve.
<h3>What is chordae tendineae ?</h3>
The chordae tendineae are thin, strong, inelastic fibrous cords that run from the free edge of the atrioventricular valve cusps (the tricuspid and mitral valves) to the apices of the papillary muscles in the right and left ventricles, respectively. The singular chorda tendinea is a rare term.
- One of the mitral valve leaflets may completely lose tension due to a primary chordae tendineae rupture (CTR), at which point it will flail. This frequently causes the MR to suddenly worsen, resulting in fainting and/or acute congestive heart failure (CHF).

Answer:
A because it is geneticly passed down
According to Mendel's Law of segregation, one copy of a gene is passed randomly from each parent to their offspring. This is why gametes have half the usual number of chromosomes. The Law of independent assortment states that different genes are not connected. In other words, the gene for eye color is not influenced by, nor does it influence, the gene for hair color. This allows gametes to form with a random mixture of traits. The cell division that creates gametes according to these principles is known as meiosis.
