Class 11 NEET Biology Excretory Products and Their Elimination

(d) : Reabsorption is a process by which useful constituents of glomerular filtrate are returned into the blood streams. It occurs in convoluted tubules (proximal convoluted tubule) as well as loop of Henle. Basically loop of Henle, in association with vasa rectae, plays an important role in the counter current mechanism (the process which makes urine hypertonic, i.e., more concentrated). Therefore, if Henle's loop was absent from mammalian nephron the urine will be more dilute.
