Components of K+ excretion in the terminal CCD. The barrel shaped structures represent the terminal CCD. Reabsorbing Na+ faster than Cl− in the CCD creates the lumen negative voltage that drives the net secretion of K+. J.H.M. Groeneveld et al.

Non-invasive estimate of the flow rate in the terminal CCD. The barrel-shaped structure represents the CCD. When ADH acts, the Posm and the osmolality in the luminal fluid of the CCD are equal (represented as 300 mOsm/kg H2O for easy calculation). J.H.M. Groeneveld et al.
