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.

Each nephron is composed of an initial filtering component (the  renal corpuscle ) and a tubule specialized for reabsorption and secretion (the renal tubule). The renal corpuscle filters out solutes from the blood, delivering water and small solutes to the renal tubule for modification.idney nephron drawing with labels of the following: the Bowman's capsule, proximal convoluted tubule, loop of Henle, descending limb of loop of Henle, ascending limb of loop of Henle, distal convoluted tubule, and collecting duct.
