Arteries serve as rapid-transit passageways from the heart because of their large radii, allowing for high velocity blood flow. Answer: C Arteries are the major sites of blood flow resistance in the vasculature due to their relatively small internal radii. Answer: E This statement is false. Arteries may carry oxygenated or deoxygenated blood depending on whether they are carrying blood away from or towards the heart.
