Multiple choice

Why is it important that the Loop of Henle passes into the Kidney's medulla?

  1. To allow waste move through by osmosis

  2. Establish an ion gradient so H2O can move through by osmosis

  3. ensure nutrients pass through

  4. establish an ion gradient

B Correct answer
Explanation

The Loop of Henle descends into the highly concentrated (hypertonic) medulla of the kidney to establish and maintain an osmotic gradient. This gradient allows water to be reabsorbed from the collecting duct and descending limb via osmosis, concentrating the urine.
