Final Answer :
E
Explanation :
Arteries carry oxygen-poor blood to the lungs (to be oxygenated), and veins carry oxygenated blood back to the heart. This is the opposite of the systemic circuit, where arteries carry oxygen-rich blood away from the heart to the body's tissues, and veins carry oxygen-poor blood back to the heart.
