WebIn the thick ascending limb (TAL), PTH increases calcium permeability and may increase the electrical driving force thereby increasing calcium reabsorption in the TAL. Finally, in the distal convolution, PTH acts to increase transcellular calcium reabsorption by increasing the activity and abundance of the apically expressed calcium channel TRPV5. hazan and shaver love quiz fullWebFour DLH modes were examined: water recycling with limited solute permeability, ideal water recycling, mixed water-solute recycling, and strict solute recycling.
