What are the chordae tendineae?Multiple choice question.bunches of muscles within the myocardiumtough fibrous cords that anchor the AV valves to the papillary musclesthe ear-like external appendages of the atriamodified muscles cells that conduct impulse during contraction

What is the function of chordae tendineae?Multiple ChoiceGenerate force to push blood through the heartOpen the AV valves during atrial contractionCarry electrical signals through the ventricular myocardiumPrevent the cusps of the AV valves from moving up into the atria

What is the function of the chordae tendineae and the papillary muscles?Multiple choice question.to pump blood from the ventricles into the arteries leaving the heartto increase surface area for the absorption of oxygen and nutrients from the blood into the heart wallto open the AV valves when the pressure of the blood in the atria is great enoughto prevent the AV valves from inverting into the atria due to the pressure of blood
