Transport of NaCl (without water) in the thin and thick ascending limb of the loop of Henle results in an interstitial osmolal gradient from 285 mosmol/kg (in the cortex, similar to plasma) to >1200 mosmol/kg in the medulla at the tip of the renal papilla. NaCl transport ...Countercurrent multiplication is something the tubule does to create the high interstitial osmolality, and a large osmolality gradient between the renal medulla and the renal cortex. The countercurrent exchange mechanism is something the vasa recta do to maintain this gradient.This video is about Steps of countercurrent multiplier | How renal medulla become hyperosmotic | loop of Henle mechanismThis video is a discussion about 6 hy...- blood is more concentrated as it dives down. ... -exchange is then opposite. -therefore, when it ascends, it reaches a dilute interstitum and loses salt.Countercurrent Multiplication. Countercurrent multiplication refers to the process by which a small osmolality difference, at each level of the outer medulla, between fluid flows in ascending and descending limbs of the loops of Henle, is multiplied by the countercurrent flow configuration to establish a large axial osmolality difference. A countercurrent mechanism is a system that uses energy to generate a concentration gradient. It can, for example, refer to the process that underpins urine concentration, namely, the mammalian kidney’s creation of hyperosmotic urine.
