Body Fluids And Circulation Question 5

Question: Emphysema damages the tissues of the lungs and slows pulmonary blood flow. This causes blood to back up, stretching and weakening the walls of the heart and blood vessels. Which of the following do you think would be most affected by this backup of blood from the lungs?

Options:

A) Aorta

B) Right atrium

C) Left atrium

D) Right ventricle

Show Answer

[d] The right ventricle pumps blood to the lungs.

Such backup of blood flow would force the right ventricle to work harder.
