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.

A countercurrent multiplication loop is a system where fluid flows in a loop so that the entrance and exit are at similar low concentration of a dissolved substance but at the far end of the loop there is a high concentration of that substance.he exchange of heat in this diagram (1) is an example of countercurrent exchange. In this example the cold water requires the birds circulatory system to recycle heat and minimize heat loss through the skin.
