Fig. 2. Net fluid movement in isolated perfused snake proximal renal tubules.
Composition of solution in lumen and bath in terms of sodium and chloride and
of substitutes for them is shown at sides of figure for each experiment. Each
bar represents the mean ± S.E.M. (N=6-13) of net
fluid movement with lumen and bath compositions shown
(Dantzler, 1978; based on data
from Dantzler and Bentley,
1978a).
