Pulmonary surfactant, a mixture consisting of phospholipids (PL) and proteins, is secreted by type II cells in the lungs of all air-breathing vertebrates. Virtually nothing is known about the factors that control the secretion of pulmonary surfactant

Typhlonectes natans empty their lungs in a single extended exhalation and subsequently fill their lungs by using a series of 10-20 inspiratory buccal oscillations. These animals always use this breathing pattern, which effectively separates inspirato

SYNOPSIS. Pulmonary surfactant is a mixture of phospholipids (including disaturated phospholipids), cholesterol and proteins lining the air-liquid interface within the lung. Surfactant acts to reduce surface tension, thereby increasing lungcompliance

Body composition in developing animals has been extensively investigated in fish larvae and bird embryos. However, no studies to date have attempted to determine whole-animal body composition or lean body mass (MLB) in developing amphibians. The pres

The lungs of all air-breathing vertebrates contain a form of pulmonary surfactant that lines the alveolar air-water interface where it modifies the interfacial surface tension. These pulmonary surfactants all consist of varying amounts of phospholipi

We examined the composition and function of pulmonary surfactant located within the faveolar and saccular regions of the garter snake Thamnophis ordinoides and the rattlesnake Crotalus atrox lung. While the faveolar region is well vascularized and se

Lung structure and function vary widely among vertebrates. Despite their diversity, all lungs are internal, fluid-lined structures that change volume and hence face similar biophysical problems. For example, if the surface tension of the fluid lining

Tail autotomy, an effective antipredator adaptation that enhances survival, may have attendant costs for the surviving prey. One potential cost not previously addressed in long-tailed, lungless salamanders that sacrifice the majority of their body ma

Mammalian lungs secrete a mixture of surface-active lipids (surfactant), which greatly reduces the surface tension of the fluid coating the inner lung surface, thereby reducing the risk of collapse upon deflation and increasing compliance upon inflat

SYNOPSIS. New data on resting metabolism, aerobic capacity, respiratory morphology and bimodal breathing capacities offour caecilian species were combined with previously known data on caecilian and amphibian biology to discern differing or unifying
