I am a student studying the cardiac
system, and have a question about coronary
bypass, and I hope it does not sound too
dumb. Why is the saphenous vein used for
the bypass? It seems to me that this (or
any) vein is insufficient because it it
designed differently from an artery (with
the one way valves, for one thing). Why
isn't another artery used for bypass
surgery? How can a vein do the same work
as an artery does? Thanks.
