Sure, if it does.  But the gut is constantly and actively moving nutrients 
across (if it is working), and that causes an osmotic gradient from the gut 
into the tissue, too.  

Classic breakdown occurs in anterior enteritis, when the movement of 
nutrients, etc., from the small intestine ceases, and you can run fluids IV 
in by the truckload, and drain them all out the nose via a nasogastric tube 
as they reflux back into the stomach.  Wanna see some fluid crossing 
membranes?  You can drain off several gallons per hour in a really nasty 
case...
