Which blood vessels carry blood away from the heart? I thought it was arteries, and I checked on the internet and the websites also say it is arteries but the answer in the book says veins. i have checked and re-checked that I haven read it properly and it says veins so could it be possible that the book has a mistake. It is the AQA Biology Revision Guide Or have I just completely misunderstood the question or the whole concept??? please explain thanks for reading my confused thoughts
