.... Although that resulted in a proportionally higher increase in pulmonary blood flow, the R–L shunt was maintained. While the systemic compliance of large arteries was the most relevant factor in regulating arterial systemic blood pressure, peripheral conductance of pulmonary circulation was the major factor...

... in Trachemys scripta while underwater. Additionally, as the respiratory system of T. scripta possesses a well-developed post-pulmonary septum (PPS), we investigated its role by analyzing the breathing mechanics of lungs with and without their PPS attached. Static compliance was significantly increased...

... compliance. In spite of large deflections of the perches and consequent substantial energy absorption, frogs were able to regain some of the energy lost to the perch during the recoil. Takeoff velocity was robust to changes in compliance, but was lower than when jumping from flat surfaces. This highlights...

... data available on the structural and functional adaptations of the marine mammal respiratory system. The aim of this research was to investigate the anatomical (gross) and structural (compliance) characteristics of excised marine mammal tracheas. Here, we defined different types of tracheal structures...

..., grass and leaves. Anoles therefore often use compliant perches that could alter jump performance. In this study we conducted a small survey of the compliance of perches used by the arboreal green anole Anolis carolinensis in the wild ( N =54 perches) and then, using perches within the range...

... to Boyle's law. Moreover, the swimbladder volume at a given depth also depends on the compliance of the swimbladder wall, but this latter factor has been investigated in only a limited number of species. In this study, changes in the volume of the zebrafish swimbladder were observed both in vitro and in situ...

... ligation (LAL) or arterial load via right vitelline artery ligation (VAL) in Hamburger-Hamilton (HH) stage 21 chick embryos. Embryos were reincubated for 1 h (HH21), 14 h (HH24) or 30 h(HH27). At each stage we measured simultaneous dorsal aortic blood pressure and flow, and calculated arterial compliance...

..., we explore quantitatively two of the more common of these explanations: (i) that strength can be traded against extensibility in allowing stretchy organisms to withstand transient wave forces, and (ii) that greater compliance (and thus longer organism response times) allows universally...

Homologous jaguar and tiger joints had limited flexion capacities, but greater compliances. The data suggest that flexion resistance may be controlled...

Two distinct mechanisms for resisting flexion moments in the terrestrial species were presented. Considering the available literature on flexion resistance in the intervertebral...
