...Lucas A. Zena; Glauber S. F. da Silva; Luciane H. Gargaglioni; Kênia C. Bícego ABSTRACT Anurans regulate short-term oscillations in blood pressure through changes in heart rate ( f H ), vascular resistance and lymphatic f H . Lung ventilation in anurans is linked to blood volume homeostasis...

...Michael S. Hedrick; Stanley S. Hillman; Robert C. Drewes; Philip C. Withers SUMMARY Vertical movement of lymph from ventral regions to the dorsally located lymph hearts in anurans is accomplished by specialized skeletal muscles working in concert with lung ventilation. We hypothesize that more...

...Colleen G. Farmer; David R. Carrier ABSTRACT The pelvis of crocodilians is highly derived in that the pubic bones are isolated from the acetabulum and are attached to the ischia via moveable joints. We examined the possible role of this unusual morphology in lung ventilation by measuring...

...David R. Carrier ABSTRACT Although the intercostal muscles play an important role in lung ventilation, observations from fishes and ectothermic tetrapods suggest that their primary function may be locomotion. To provide a broader understanding of the role these muscles play in locomotion, I...

...Peter L. Lutz; Ann Bergey; Michael Bergey ABSTRACT Oxygen consumption, lung ventilation, plasma ion concentrations and osmolality, venous blood acid-base status and gas tensions were measured in unrestrained loggerhead sea turtles in sea water at 10, 15, 20 and 30 °C at rest and during routine...

...David R. Carrier ABSTRACT Patterns of muscle activity during lung ventilation, patterns of innervation and some contractile properties were measured in the hypaxial muscles of green iguanas. Electromyography shows that only four hypaxial muscles are involved in breathing. Expiration is produced...

... different combinations of oxygen and carbon dioxide indicated that lung ventilation frequencies were more labile than gill ventilation frequencies. The maximum change in lung ventilation rates was 849% above controls whereas the largest change in gill ventilation frequency was 27%. Exposure of reedfish...
