Question

If due to some injury the chordae tendineae of the tricuspid valve of the human heart is partially non-functional, what will be the immediate effect?

• A. The blood will tend to flow back into the left atrium.
• B. The flow of blood into the aorta will be slowed down.
• C. The pacemaker will stop functioning.
• D. The flow of blood into the pulmonary artery will be reduced.

Answer 1

The correct option is D

The flow of blood into the pulmonary artery will be reduced.

If due to injury the chordae tendineae of the tricuspid valves of the human heart is partially non-functional, the flow of blood into the pulmonary artery is reduced due to backflow of blood into the right atrium.
