Question

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

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

Answer 1

The correct option is D Flow of blood into the pulmonary artery will be reduced

Tricuspid valve is found in right arterio - ventricular septum, this prevents the backflow of blood into right atrium. Chordae tendinae is muscles which regulates the movement of tricuspid valves. Any injury to chordae tendinae will effect working of tricuspid valves and and as a result flow of blood into pulmonary artery will be reduced.
