WebThe reabsorption depends on active sodium reabsorption but not on the presence or reabsorption of bicarbonate (Brokl et al., 1994). Regulation of water reabsorption occurs not in the proximal tubule, though, but in more distal nephron segments. As noted above, birds, like mammals, are able to produce a urine more concentrated than the plasma. WebIt was concluded that HCO3- reabsorption in the proximal tubule was mediated by H+ secretion, but that carbonic anhydrase located in the luminal membrane of the cell …
