Vessels usually conveying oxygenated blood (8)

I believe the answer is:

arteries

(Other definitions for arteries that I've seen before include "Major thoroughfares for important traffic" , "Blood vessels leading from the heart" , "Vessels that carry blood from the heart to the body" , "Blood vessels - major roads" .)

I've seen this clue in The Times.
