Available in PDF, EPUB and Kindle. Book excerpt: This monograph has attempted to bring together morphological and physiological studies of reptilian lungs, to analyze the nature of the resulting correlations, and to risk some speculations regarding the evolution of reptilian lung structure. Central to this work is the morphometric evaluation of the lungs in two species of lizard: "the teju (Tupinambis nigropunctatus Spix) and the savanna monitor (Varanus exanthema ticus [Bosc]) which is presented here for the first time. These two species are similar in body form, and both are diurnally active predators, but their lungs are of basic ally different structural types. The teju possesses relatively small, single-chambered (unicameral) lungs in which the homeycomb-like (faveolar) parenchyma is more or less evenly distributed along their length. In the monitor the lungs are large and many-chambered (multicameral), the individual chambers connecting to an unbranched, intrapulmonary bronchus. The parenchyma is in the form of shallow cubicles (ediculae), which are elaborated on the intercameral septa. The parenchyma is heterogeneously distributed within the lungs, tending to be most concentrated near the intrapulmonary bronchus and the middle third of the lung length. The ventral and caudal portions of these lungs are thin-walled and highly flexible. In both species those portions of the lungs which are most exposed to air convection possess dense capillary nets which almost completely cover both sides of the parenchymal partitions. In more distal regions of the parenchy ma or of the lung, the intercapillary spaces become larger, creating a pseudo-single capillary net.

This book was released on 2009-07-24 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hopefully, this book will be taken off of the shelf frequently to be studied carefully over many years. More than 40 researchers were involved in this project, which examines respiration, circulation, and metabolism from ?sh to the land vertebrates, including human beings. A breathable and stable atmosphere ?rst appeared about 500 million years ago. Oxygen levels are not stable in aquatic environments and exclusively water-breathing ?sh must still cope with the ever-changing levels of O 2 and with large temperature changes. This is re?ected in their sophisticated count- current systems, with high O extraction and internal and external O receptors. 2 2 The conquest for the terrestrial environment took place in the late Devonian period (355–359 million years ago), and recent discoveries portray the gradual transitional evolution of land vertebrates. The oxygen-rich and relatively stable atmospheric conditionsimpliedthatoxygen-sensingmechanismswererelativelysimpleandl- gain compared with acid–base regulation. Recently, physiology has expanded into related ?elds such as biochemistry, molecular biology, morphology and anatomy. In the light of the work in these ?elds, the introduction of DNA-based cladograms, which can be used to evaluate the likelihood of land vertebrates and lung?sh as a sister group, could explain why their cardio-respiratory control systems are similar. The diffusing capacity of a duck lung is 40 times higher than that of a toad or lung?sh. Certainly, some animals have evolved to rich high-performance levels.

Available in PDF, EPUB and Kindle. Book excerpt: The structural and chemical limitations to respiratory gas exchange existing between the ambient medium and the cell are comprehensively treated. Beginning with an examination of the natural oscillations of respiratory gases in both terrestrial and aquatic environments, Vertebrate Gas Exchange details the structures involved in convecting the medium (air or water), the morphometrics of capillary gas transfers, and gas transfer kinetics. Important features include details on measurement techniques associated with tissue capillary supply and gas exchange kinetics.

Download or read book The Lung Air Sac System of Birds written by John N. Maina and published by Springer Science & Business Media. This book was released on 2005-12-28 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: In biology, few organs have been as elusive as the lung-air sac system of birds. Considerable progress has recently been made to fill the gaps in the knowledge. While summarizing and building on earlier observations and ideas, this book provides cutting-edge details on the development, structure, function, and the evolutionary design of the avian respiratory system. Outlining the mechanisms and principles through which biological complexity and functional novelty have been crafted in a unique gas exchanger, this account will provoke further inquiries on the many still uncertain issues. The specific goal here was to highlight the uniqueness of the design of the avian respiratory system and the factors that obligated it.

This book was released on 2011-06-24 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book encapsulates over three decades of the author’s work on comparative functional respiratory morphology. It provides insights into the mechanism(s) by which respiratory means and processes originated and advanced to their modern states. Pertinent cross-disciplinary details and facts have been integrated and reexamined in order to arrive at more robust answers to questions regarding the basis of the functional designs of gas exchangers. The utilization of oxygen for energy production is an ancient process, the development and progression of which were underpinned by dynamic events in the biological, physical, and chemical worlds. Many books that have broached the subject of comparative functional respiratory biology have only described the form and function of the ‘end-product,’ the gas exchanger; they have scarcely delved into the factors and the conditions that motivated and steered the development from primeval to modern respiratory means and processes. This book addresses and answers broad questions concerning the critical synthesis of multidisciplinary data, and clarifies previously cryptic aspects of comparative respiratory biology.
