Final answer:
The pulmonary arteries transport oxygen-poor blood from the heart to the lungs.
Step-by-step explanation:
The arteries that transport oxygen-poor blood from the heart to the lungs are the pulmonary arteries. These arteries carry deoxygenated blood away from the heart and deliver it to the lungs for oxygenation.
The other options mentioned, the aorta and coronary arteries, carry oxygen-rich blood away from the heart.
