Explanation

Loop of Henle refers to the absorption of water. The kidneys produce concentrated urine by a complex sequence of events which is known as the counter-current multiplier system. This system resides in the loop of Henle, which is a hairpin loop interposed between the proximal and distal tubules of a nephron.
