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?
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?
The correct option is A The flow of blood into the pulmonary artery will be reduced
The correct option is A:
Explanation of the correct option:
- The human heart is divided into four chambers: two atria and two ventricles. The major purpose of the bicuspid and tricuspid valves is to keep blood from flowing backwards from the ventricles to the atria on their respective sides.
- Between the right atrium and the right ventricle is the tricuspid valve. Deoxygenated blood, which originates from all regions of the body and is directed to the lungs for oxygenation, is dealt with on the right side of the heart.
- The superior and inferior vena cava of the human heart's twofold circulation deliver deoxygenated blood from all parts of the body to the right atrium. It's then transported to the right ventricle, where it's oxygenated before being supplied to the lungs via the pulmonary artery.
- The tricuspid valve protects the entrance between the right atrium and right ventricle. It gets its name from the three flaps that resemble cusps. Chordae tendineae are fibrous structures that keep the flaps in place.
- When the chordae tendineae contract, they pull all three cusp down, allowing blood to flow into the right ventricle and opening the tricuspid valve. If the chordae tendineae are injured, a backflow of blood into the atria will occur immediately.
- As a result, blood flow into the pulmonary artery will be diminished since blood will continue to return to the atria.
Explanation of the incorrect option:
Option B:
Chordae tendineae is held tightly to tricuspid valve that guard the opening of right atrium and right ventricle and injury in chordae tendineae will not affect blood flow in left atrium.
Option C:
Injury in chordae tendineae will not affect blood flow in aorta.
Option D:
Functioning of pacemaker is not controlled by chordae tendineae so injury in chordae tendineae will not affect pacemaker.
Final answer: If due to some injury, the chordae tendineae of the tricuspid valve of the human heart is partially non-functional then the flow of blood into the pulmonary artery will be reduced
