Fig. 6. Plasma concentrations (mmol l-1) of Na+ (
),
Cl- (
) and urea ([UNK]) following controlled haemorrhage of
approximately 5.7% of total blood volume in Scyliorhinus canicula
(N=6). Results are expressed as means + S.E.M. Statistical
comparisons were made with time zero. Plasma, Na+, Cl-
and urea concentrations did not change significantly (Student's
t-test).
