There are many blood vessels on the surface of the uterus which 'feed' the placenta. In the umbilical cord there are usually two arteries and one vein, the arteries taking deoxygenated blood from the fetus to the placenta and one vein taking oxygentated blood fron the placenta to the fetus.

Yes, when rats are born they each come attached to their own placenta, which the mother then licks off and eats. There is one placenta for each baby rat, but if the mother rat doesn't expel the placenta it can rot inside her and make her sick even to the point of death. Baby rats are connected to their placenta by their umbilical cord. Sources: I breed and research rats=)
