Question
Which is a valid comparison between arteries and veins?
Markscheme
C
Examiners report
This question discriminated very well. Good candidates were able to distinguish arteries from veins. Some teachers complained that arteries carry oxygenated blood and veins deoxygenated blood, but this is not true for pulmonary and umbilical arteries and veins.
