==The Loop of Henle==

The loop of henle basically consists of two parallel limbs which descend from the cortex into the medulla.  They are joined at the bottom and as such the flow moves down one limb and up the other in opposite directions.  This sets up a counter current exchanger and allows the loop of henle to be the major site of water reabsorption along the nephron.  It has three parts; the thin decsending limb, the thin ascending limb and the thick ascending limb
