Answer 1

The loop of Henle’s is a counter current exchanger because it creates a concentration gradient rather than simply maintaining it. The given statement is false.

Further explanation:

Loop of Henle, in kidneys, refers to the portion of the nephron which leads from the proximal convoluted tubule and goes to the distal convoluted tubule. It is a long and a U-shaped portion of the tubule which basically collects the urine and it is observed in bird, reptiles, and mammals. The chief function of this part is to recover water as well as sodium and chloride ions from the urine. This allows the generation of urine which is far more concentrated as compared to blood and limits the amount of water required as intake of survival.

Counter current multiplication found in the kidneys refers to the process of using energy to produce an osmotic gradient which allows the body to reabsorb water from the tubular fluid as well as generate concentrated urine. This mechanism avoids the body from generating liters and liters of dilute urine. This usually occurs in nephrons, nephrons are of two kinds, superficial cortical and juxta-medullary nephrons.

Answer 2

true

The loop of Henle is adequately long enough to descend into the medulla before looping back into the cortex. It helps to establish a concentration gradient based on the permeability of different parts of the loop.
