Choose the best answer.

Her repeated pulmonary infections have weakened the right side of her heart, so it is enlarged.

a) Since blood is moving between her atria, the blood in her ventricles and arteries is staying where it is, distending those structures.

b) Since she has a pulmonary infection, more blood is being diverted to her lungs; this distends her pulmonary trunk and leaves less blood in the systemic circuit.

c) Since blood is moving from her systemic circuit into her pulmonary circuit, the pulmonary circuit is distended and the systemic circuit is low on blood.

Abram Wiley · Answer 1

Option B

Explanation:

Failing of right side is usually caused by failure of left side of heart. Malfunctioned right side of the heart loses its power of efficient pumping and as a result of this the blood is pumped back into the lungs. This backward flow backs up in the veins thereby causing the fluid to swell and hence the swelling in various body parts such as legs, liver, GI tracts, abdomen etc.

Hence, option B is correct

Alonzo Long · Answer 2

Answer: Option B.

Explanation:

Pulmonary infection is also lung infection. It can be caused by virus, bacteria or fungi.

A person can be infected when he breathing the pathogens from the air. A person with pulmonary infection can have right sided heart failure.

Right sided heart failure occur when because of left sided heart failure. The left sided failure occur when the left ventricle loses power to pump blood to the rest of the body. As a result, blood is pump to the lungs which weaken the right side of the heart and this lead to right side heart failure.
