Loop of Henle -- This segment of the nephron plays a major role in the countercurrent exchange/multiplier system of water conservation. It has the ability to concentrate solutes, increase osmotic pressure, and conserve or excrete water.It also serves as a sight of Na, K, and Cl conservation.oop of Henle -- This segment of the nephron plays a major role in the countercurrent exchange/multiplier system of water conservation.

Pump: The Na+/K+/2Clâ transporter in the ascending limb of the loop of Henle helps to create a gradient by shifting Na+ into the medullary interstitium. The thick ascending limb of the loop of Henle is the only part of the nephron lacking in aquaporinâa common transporter protein for water channels.
