Pulmonary CO-diffusing capacity (D l CO), lung volume, pulmonary perfusion and O2-uptake were measured by non-invasive techniques in the lizardsVaranus exanthematicus andTupinambis teguixin (mean body weight 2.2 kg for both species). The CO-diffusing capacity was at 25–27°C 0.059 mlstpd·kg−1·min−1·Torr−1 inVaranus, which is 47% greater than the value of 0.040 mlstpd·kg−1·min−1·Torr−1 inTupinambis. The lung volume ofVaranus was 36 ml·kg−1 and that ofTupinambis 20 ml·kg−1. At 35–37°C the… CONTINUE READING
