If loop of Henle were absent from mammalian nephron which one of the following is to be expected?
Correct answer: D. The urine will be more dilute
- A. There will be no urine formation.
- B. There will be hardly any change in the quality and quantity of urine formed
- C. The urine will be more concentrated
- D. The urine will be more dilute
Explanation
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.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
