The chordae tendinae
a. connect the atria to the ventricles
b. are founf in the interventricular septum
c. are part of the conducting system of the heart
d. connect the flaps of the av valves to the papillary muscles
e. are a part of the myocardium

The correct answer to the question: The chordae tendinae:, would be, D: connect the flaps of the AV valves to the papillary muscles.

Explanation:

The atrial chambers and ventricular chambers of the heart, are not simply freeway connected without any limitations between them. If this were so, the heart would burst. Instead, on the division between the two atria, and the two ventricles, stand the AV valves, or atrioventricular valves: the tricuspid, or atrioventricular valve, and the bicuspid, or mitral valve. These two valves are the ones responsible for ensuring the correct passage of blood from the atria to the ventricles, and prevents blood from regurgitating to the atria once the ventricles are full. In order to do this, these valves have fibrous tissue connectors that link their flaps to the papillary muscles. These connective tissue links are known as the chordae tendinae.
