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

  1. A
    The flow of blood into the pulmonary artery will be reduced.
  2. B
    The flow of blood into the aorta will be slowed down.
  3. C
    The pacemaker will stop working.
  4. D
    The blood will tend to flow back into the left atrium.

Solution & Step-by-step Explanation

The tricuspid valve is located between the right atrium and right ventricle. Chordae tendinae prevent the valves from flapping back into the atria during ventricular contraction. If they fail, blood will leak back from the right ventricle into the right atrium, thereby reducing the volume of blood pumped into the pulmonary artery.
