WebMay 3, 2024 · Specifically, it acts in the distal convoluted tubule (DCT) and collecting ducts (CD). During states of increased plasma osmolality, ADH secretion is increased. ADH acts through a G-protein coupled receptor to increase the transcription and insertion of Aquaporin–2 channels to the apical membrane of the DCT and CD cells. Consequently, … WebCollecting tubules are quite large, with walls formed of cuboidal epithelium. They’re larger than the DT and the nuclei of their mural cells bulge somewhat into the lumen.

"WebThe filtrate entering the proximal convoluted tubule is 300 mOsm/L, which is the same osmolarity as normal plasma osmolarity. In the proximal convoluted tubules, all the glucose in the filtrate is reabsorbed, along with an equal concentration of ions and water (through cotransport), so that the filtrate is still 300 mOsm/L as it leaves the tubule.
