alleryAmong all the blood vessels, which type carries deoxygenated blood even though its general class usually carries oxygenated blood?
APulmonary vein
BCoronary artery
CPulmonary artery
DAorta
Answer & Solution
Correct answer: C. Pulmonary artery
1. Arteries normally carry oxygenated blood, with one lone exception.
2. Option A (pulmonary vein) is the vein that breaks the usual rule, but it carries oxygenated blood, so it is a trap.
3. Option B (coronary artery) carries oxygenated blood to the heart muscle, as expected of an artery.
4. Option D (aorta) carries oxygenated blood to the body, again the normal case.
5. The one artery that carries deoxygenated blood goes from the right ventricle to the lungs.
6. That vessel is the pulmonary artery, option C.
