Fig. 3. (A) Number of zebrafish larvae showing partial deoxygenation of the blood
under normoxic conditions (filled bar) and the number of animals, showing
complete oxygen saturation (open bar). (B) Oxygen saturation of the blood in
the ventricle of normoxic zebrafish larvae
(PO2=20 kPa). Values are means ±
S.E.M. *Significant differences from full saturation.
N values are given in parentheses below each symbol.
