 This is the final segment of the nephron, and it has an important role in electrolyte and water absorption.

 The collecting duct is under the influence of arginine vasopressin (anti‐diuretic hormone – ADH), which controls the final urine osmolality (concentration).

 During states of dehydration, ADH is released from the posterior pituitary, resulting in the insertion of aquaporin channels into the membrane of the cells of the collecting duct.These channels allow the absorption of water, resulting in a concentrated urine.
