femoral artery: body AS copy machine:?

Please solve the following SAT analogy:

your femoral artery:your body
as
copy machine: is to what?

the answer: a school!

not having a copy machine makes things strongly difficult I must say. maybe the problem is we haven't given a proper name to our copy machine, so that's why it keeps malfunctioning and making horrible noises. What about:
Delilah?
Raquel?
Ernie?
Fred?
Boomer?

Any of those names suffice?
