| yeah, I noticed about the umbilical cord after I made the test, and can't find the button to edit that. and it's a shame, cause people are going to get wrong answers :(
and yeah, it would have been smarter to just label it "vessels going TO the heart" or something like that. but in general, veins have the deoxygenated blood. the pulmonary ones are just an exception.
thanks for the corrections though! |
