WebThe collecting duct can maintain large osmotic gradients; however, this capacity is limited, and the minimal osmolality of the urine is approximately 50 mOsm/kg H2 O. If more dilute fluid is delivered to the collecting duct, this water will be reabsorbed even in the absence of ADH, as occurs in psychogenic polydipsia and in beer potomania. Web30 apr. 2016 · The two main factors that regulate AQP2 are environmental osmolality and AVP . Although the cortico-medullary osmolality gradient has a greater influence over AQP2 than AVP, the regulatory mechanisms controlling water balance through AQP2 are complex and are still not well understood.
