In the kidney of the amphibian, Necturus, appreciable quantities of inulin and human serum albumin are transported from the tubular lumen of the proximal tubules into the blood. These findings suggest that inulin may not be a satisfactory indicator for measuring net water movement in the kidney of this species.
