ADH and Aquaporin Insertion in the Collecting Duct
Captions available
The idea
Antidiuretic hormone, per Bio 2935, inserts aquaporin channels into the kidney's collecting duct, letting water move out along the gradient the loop of Henle, per Bio 3239, established.
In practice
Without ADH, the collecting duct stays impermeable despite the surrounding gradient being present.
Where people slip
The gradient, per Bio 3239, sets the concentrating potential — ADH determines how much of it the duct uses.
