Respiratory gas exchange in insects occurs via a branching tracheal system. The entrances to the air-filled tracheae are the spiracles, which are gate-like structures in the exoskeleton. The open or c
Metabolic rate and respiratory gas exchange patterns vary significantly both between and within species, even after a number of biotic and abiotic factors are taken into account. This suggests that su
No significant differences were found between SO and intact individuals in either density-dependent phase (P>0.60). Cutting the connectives had a significant effect on gas exchange pattern in solitary

Mammals regulate their brain tissue PO2Â tightly, and only small changes in brain PO2Â are required to elicit compensatory ventilation. However, unlike the flow-through cardiovascular system of verteb
