Question

which of the following vessels transports deoxygenated blood from the heart to the lung?
a pulmonary artery
b aorta
c pulmonary vein
d vena cava

Explanation:

To solve this, we analyze each option:

• Option A: The pulmonary artery carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.
• Option B: The aorta carries oxygenated blood from the left ventricle to the rest of the body, not to the lungs with deoxygenated blood.
• Option C: The pulmonary vein carries oxygenated blood from the lungs back to the heart (left atrium), so it's not transporting deoxygenated blood to the lungs.
• Option D: The vena cava (superior and inferior) brings deoxygenated blood from the body to the right atrium of the heart, not from the heart to the lungs.

So the correct vessel is the pulmonary artery.

Answer:

A. Pulmonary artery
