An important adaptation to hypoxia is a regulated reduction in body temperature (Tb; anapyrexia), presumably because it lowers metabolic rate when oxygen supply is limited. Although this beneficial response occurs in organisms ranging from protozoans

Hypoxia rapidly increases hematocrit (Hct) in anuran amphibians by reducing plasma volume, but the mechanism(s) mediating this response is unknown. We tested the hypothesis that, during hypoxia, plasma volume is reduced by impaired lymph heart (LH) f

Fluid balance in amphibians is regulated, in large part, by arginine vasotocin (AVT). One important action of this hormone is to facilitate water uptake by increasing the water permeability of the skin. Cutaneous blood flow also affects water uptake,

We tested experimentally the hypothesis that decreasing capillary red blood cell (RBC) density (dRBC) reduces the tissue diffusing capacity of frog skin to CO (DtiCO) and O2 (DtiO2). The effects of dRBC on CO2 transport were also assessed. C18O, O2,

1. In organisms ranging from paramecia to mammals, hypoxia elicits a regulated decrease in body temperature (Tb). A decrease in Tb is an important adaptation to hypoxia primarily because it lowers metabolic rate when oxygen supply is limited, thus fa

Many different flow patterns have been described through the central circulation of crocodilian reptiles. We tested the hypothesis that the vagus nerve stimulation promotes right-to-left (R-L) shunting in the alligator. Flow patterns were investigate

In adult mammals and birds, the right and left sides of the heart are normally separate. Intracardiac shunting, which is usually detrimental, results only from congenital abnormalities of the heart and great vessels. In contrast, intracardiac shuntin

In the amphibian Bufo marinus, progressive hypoxia below a critical PO2 elicits a transient 50% increase in O2 consumption that coincides with the onset of lactate formation. The present study was designed to test the hypothesis that lactate causes t

Two principal hypotheses account for right-left (R-L) intracardiac shunting in reptiles. The “pressure shunting” hypothesis proposes no functional separation between the ventricular cava during systole. The “washout shunting” hypothesis sugge
