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?
Correct answer: D. The flow of blood into the pulmonary artery will be reduced
- A. The flow of blood into the aorta will be slowed down
- B. The 'pacemaker' will stop working
- C. The blood will tend to flow back into the left atrium
- D. The flow of blood into the pulmonary artery will be reduced
Explanation
The tricuspid valve is located on the right side of the heart and prevents backflow of blood from the right ventricle into the right atrium. If the chordae tendinae are partially non-functional, the tricuspid valve may not close properly, leading to regurgitation of blood from the right ventricle into the right atrium. This can result in a reduction of blood flow into the pulmonary artery, which carries blood from the right ventricle to the lungs.

About Circulation
The circulatory system covers the chambers, valves and conducting pathway of the human heart, along with the cardiac cycle and control of heartbeat. It compares arteries, veins and capillaries by structure and function, and explains how the lymphatic system returns tissue fluid, transports absorbed fats and supports immunity.
