what happens if you cut a vein? like pic related, if you were to take a knife and slice this thing in half, what happens? does the receiving end shrivel up and die? what about all the little branching paths? Do they deflate? and when it heals over, does it reconnect two the two halves, or does it just seal the ends of each? will a new vein grow to replace it if that's the case?
