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?

Options

(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

Correct Answer:

The flow of blood into the pulmonary artery will be reduced

Explanation:

Tricuspid valve is the valve in the heart between the right atrium and right ventricle. The valve opens to alow blood to flow from atrium into the ventricle. Thus if tricuspid valve is partially non-functional, then the flow of blood into the pulmonary artery will be reduced.
