| Abstract | LENFANT, C., R. ELSNER, G. L. KOOYMAN, AND C. M. DRABEK. Respiratory function of blood of the adult and fetus Weddell seal Leptonychotes weddelli. Am. J. Physiol. 2 16(6) : 1595-l 597. 1969.-The respiratory function of the blood of the adult (A) and fetus (F) Weddell seal was studied in four specimens. The average hematocrit, hemoglobin and oxygen capacity were, respectively, in A and F: 61.5 %, 23.7 g, and 3 1.6 vol %, and 57.5%, 20.8 g, and 27.7 vol %. Studies of the OzHb dissociation curve showed P&7.4) = 28.5 and 22.1 mm Hg, respectively, in A and F. The Bohr effect was ,613 in adults and -.674 in fetus. The standard HCO,was higher in the fetus than in the adult (30.1 and 26.6 mu) and the buffering capacity between pH 7.3 and 7.6 was 19.5 mu in A and 18.2 mM in F. In two adult specimens, the blood volume averaged 148 ml/kg of total weight and 227 ml/kg of fat and skin-free body weight. These properties appear to be very suitable to the diving habits of the Weddell seal. |
