Countercurrent Exchange

Description
Loop and duct cells require nutrients and oxygen from blood supply.
Capillaries that feed them (vasa recta) form loops like those of nephron loops in the medulla.
Incoming and outgoing blood will have similar osmolarity.
This maintains medulla concentration gradient.
