Although in reality it is a continual process, the way the countercurrent multiplication process builds up an osmotic gradient in the interstitial fluid can be thought of in two steps: The single effect. The nephrons are located in the cortex and medulla of the kidney. The location of the juxtamedullary nephron is the inner part of cortex Cortical nephrons have a longer tubule. Eighty-five percent of nephrons are cortical nephrons, deep in the renal cortex; the remaining 15 percent are juxtamedullary nephrons, which lie in the renal cortex close to the renal medulla. Juxtamedullary nephrons are named because their loops of Henle dip all the way down to the bottom portions of the medulla. There is also juxtamedullary nephrons whose longer loops of Henle pass deeply into the medulla. The percentage of juxtamedullary nephrons in kidneys is . The nephron loops of the juxtamedullary nephrons are surrounded by a looping, ladder-like blood vessel called the _____. the flow of blood to the individual Cortical nephrons have a longer tubule. Juxtamedullary nephrons have long-reach loops that penetrate deep into the medulla. In the kidneys, the countercurrent mechanism involves the interaction between the flow of filtrate through the loop of Henle of the juxtamedullary nephrons (the countercurrent multiplier) and the flow of blood through the limbs of adjacent blood vessels (the countercurrent exchanger). The cortical nephrons with only a very short or no loop of Henle do not participate in producing a urine more concentrated than the body fluid. How Juxtamedullary nephrons, unlike those farther away from the renal medulla, have long nephron loops than extend deep into the medulla. They make the Juxta means next to or near.
