Which of the heart valves contain chordae tendineae?
A) The aortic and pulmonary semilunar valves
B) The tricuspid and mitral valves
C) The aortic and mitral valves
D) The pulmonary and tricuspid valves
E) All of the heart valves
Chordae Tendineae
Heart strings that connect the papillary muscles of the heart to the tricuspid and mitral valves, facilitating valve function.
Tricuspid Valve
A valve in the heart that lies between the right atrium and the right ventricle, preventing backflow of blood.
Aortic Valve
A valve in the heart between the left ventricle and the aorta that prevents blood from flowing back into the ventricle after it has been pumped out.

Final Answer :
B
Explanation :
The tricuspid and mitral valves are the atrioventricular valves, which connect the atria and ventricles. They contain chordae tendineae, which attach to the papillary muscles in the ventricles and prevent the valve flaps from flipping into the atria during ventricular contraction. The semilunar valves (aortic and pulmonary) do not contain chordae tendineae.
