sodium and chloride ions from the ascending limb of the loop of Henle
B active transport of sodium and chloride ions from the ascending limb of the vasa recta
C the ascending limb of the loop of Henle to be permeable to water
D the vasa recta to be impermeable to water E both A and B

1 The antidiuretic hormone
0
A increases the permeability of the collecting ducts to water
B is secreted in response to low concentrations of potassium ions in the extracellular fluid.
C causes the kidneys to produce a larger volume of relatively solute-free urine
