* [[Endocrine System - Pituitary Gland - Anatomy & Physiology #Posterior Pituitary Gland| ADH]] causes these vesicles to attach to the principal cell membranes.

* This is how ADH works.
* This is how ADH works.
** The higher its concentration the more AQP2 avaiable to water within the collecting duct
** The higher its concentration the more AQP2 bind to principal cell membranes therefore the more AQP2 available to water within the collecting duct
** The more water is reabsorbed
** The more water is reabsorbed
** Thanks to the gradient created by the hypertonic medulla which is present due to the countercurrent multiplier in the [[Loop Of Henle - Anatomy & Physiology| Loop of Henle]]
