Vertebrate Gas Exchange by Robert G. Boutilier Pdf

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.

The Vertebrate Gas Transport Cascade by J. Eduardo P. W Bicudo Pdf

This volume presents contributions given at the international symposium on The Vertebrate Gas Transport Cascade: Adaptations to Environment and Mode of Life, held in São Sebastião, São Paulo, Brazil from September 10-15, 1991. Recent developments in the field and the unifying principles of basic respiratory mechanisms are covered, and reviews in major areas of respiratory physiology are complemented by recent experimental data. Principal topics discussed include conditions for gas exchange in selected special environments, ventilation of the gas exchanger, diffusing capacity and exchange between respired medium and blood, respiratory pigments and oxygen transport by blood, cardiovascular function and oxygen transport by blood, oxygen delivery to tissue, and transition to anaerobic metabolism. The Vertebrate Gas Transport Cascade: Adaptations to Environment and Mode of Life will be a useful addition to the reference collections of respiratory physiologists, comparative physiologists, cardiovascular physiologists, experimental biologists, students, and others interested in the topic.

Cardio-Respiratory Control in Vertebrates by Mogens L. Glass,Stephen C. Wood Pdf

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.

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.

Comparative Physiology of Vertebrate Respiration by George Morgan Hughes Pdf

This book is a concise study of the structure and function of vertebrate respiratory systems. It describes not only the individual organ systems, but also the relationship of these systems to each other and to the animal's environment. For example, the author emphasizes that a proper understanding of respiration involves a consideration of the external environment as a source of oxygen as well as the biochemistry of the cell; and, from the evolutionary point of view, that physiological changes in the respiratory and circulatory systems are dominated by the origin of the land habit. The author's approach to the subject exemplifies that trend to the amalgamation of Zoology and Physiology, which has become increasingly marked at universities and schools in recent years. This synthesis requires, broadly, a knowledge of classical comparative anatomy, ecology, evolution, physiology and biochemistry; an enormous task, but nevertheless one in which the zoologist holds a central position. This book indicates the nature of such an eclectic approach, with the animal, in its environment and its evolution, as its focal point. Covering a rapidly changing field of research the author refers to many recent views and indicates where these differ from those commonly accepted.

Respiration and metabolism of embryonic vertebrates by Roger S. Seymour Pdf

The papers in this volume were presented at an international symposium, held in South Australia on September 8-10, 1983. The purpose of the meeting was to present the comparative physiology of gas exchange, water balance and energet ics of developing vertebrate embryos. contributions were invited from leading research workers in an attempt to represent the forefront of investigation of all vertebrate classes and to promote a broadly comparative approach to the study of embryonic physiology. These proceedings therefore reflect the current level of research activity focus ing on each group of vertebrates. While considerable expansion and specializa tion has occurred in the area of avian embryos over the last decade, work on reptilian embryos is less developed and that on fish and amphibians is still in its infancy. Although a great deal is known about respiration and metabolism in embryos of placental mammals, the physiology associated with the curious mode of development of monotreme and marsupial embryos has not been examined until recently. In this symposium. the well-studied vertebrate classes are repre sented primarily by specific research papers that document original work. These are balanced by more extensive reviews of the lesser known classes.

Respiratory Physiology of Vertebrates by Göran E. Nilsson Pdf

How do vertebrates get the oxygen they need, or even manage without it for shorter or longer periods of time? How do they sense oxygen, how do they take it up from water or air, and how do they transport it to their tissues? Respiratory system adaptations allow numerous vertebrates to thrive in extreme environments where oxygen availability is limited or where there is no oxygen at all. Written for students and researchers in comparative physiology, this authoritative summary of vertebrate respiratory physiology begins by exploring the fundamentals of oxygen sensing, uptake and transport in a textbook style. Subsequently, the reader is shown important examples of extreme respiratory performance, like diving and high altitude survival in mammals and birds, air breathing in fish, and those few vertebrates that can survive without any oxygen at all for several months, showing how evolution has solved the problem of life without oxygen.

Adaptation to Altitude-Hypoxia in Vertebrates by P. Bouverot Pdf

Adaptation to altitude hypoxia is characterized by a variety offunctional changes which collectively facilitate oxygen trans port from the ambient medium to the cells of the body. All of these changes can be seen at one time or another in the course of hypoxic exposure. Yet, as already stressed (Hannon and Vogel, 1977), an examination of the literature gives only a sketchy and often conflicting picture of the exact nature of these changes and how they interact as a function of exposure duration. This is partly because of the limited number of variables explored in a given study, but it is also attributable to differences in experimental design, differences among species in susceptibility to hypoxia, nonstandardized experimental conditions, lack of proper control of physical (e. g. , temperature) and physiological variables (e. g. , body mass), failure to take measurements at key periods of exposure, and gaps in knowledge about some fundamental mechanisms. Furthermore the available data on animals native to high altitude are meager and/or inconclusive. Extensive further work under well-controlled experimental conditions is required before a detailed picture can be made. Nevertheless, it has been a guiding principle in the prepara tion of this monograph rather to summarize the vastly dis persed material that constitutes the comparative physiology of adaptation to high altitude into a coherent picture, than to provide a comprehensive survey of the field.

Endothelial Biomedicine by William C. Aird Pdf

The endothelium, the cell layer that forms the inner lining of blood vessels, is a spatially distributed system that extends to all areas of the human body. Clinical and basic research demonstrates that the endothelium plays a crucial role in mediating homeostasis and is involved in virtually every disease, either as a primary determinant of pathophysiology or as a victim of collateral damage. The endothelium has remarkable, though largely untapped, diagnostic and therapeutic potential. This volume bridges the bench-to-bedside gap in endothelial biomedicine, advancing research and development and improving human health. The book is the first to systematically integrate knowledge about the endothelium from different organ-specific disciplines, including neurology, pulmonary, cardiology, gastroenterology, rheumatology, infectious disease, hematology-oncology, nephrology, and dermatology. It's interdisciplinary approach, which draws on expertise from such diverse fields as evolutionary biology, comparative biology, molecular and cell biology, mathematical modeling and complexity theory, translational research, and clinical medicine.

Concepts of Biology by Samantha Fowler,Rebecca Roush,James Wise Pdf

Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.
