Which statement is incorrect?
A)Juxtamedullary nephrons establish a vertical osmotic gradient in the medulla.
B)NaCl pumps of the ascending limb of the loop of Henle can establish a 1,200 mOsm/liter difference between ascending and descending limbs at any given location.
C)Countercurrent exchange allows the vasa recta to preserve the vertical osmotic gradient while supplying blood to the medullary tissue.
D)Collecting tubules of all nephrons utilize the driving force of the vertical osmotic gradient to accomplish variable H2O reabsorption under the control of vasopressin.
E)The filtrate is isotonic as it enters the loop of Henle, hypertonic at the tip of the loop of Henle, and hypotonic as it leaves the loop of Henle.

Question

Quizplus · Accepted Answer

The NaCl pumps of the ascending limb of the loop of Henle do not establish a 1,200 mOsm/liter difference; they create a smaller gradient, typically around 200 mOsm/liter, between the ascending and descending limbs at any given location.
