Yes, it does move backward up the ducts again, that way the alveoli can 
sense how much milk is left and change the production speed accordingly. 
The only thing that does not reverse as far as we know is the fat seems 
to stay in the milk rather than going back into the milk making cell 
(lactocyte).
