Regulation of Tissue Oxygenation, Second Edition
Author: Roland N. Pittman
Publisher: Biota Publishing
ISBN: 1615047212
Category : Medical
Languages : en
Pages : 117
Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

The Vertebrate Gas Transport Cascade
Author: J. Eduardo P. W Bicudo
Publisher: CRC Press
ISBN: 9780849349768
Category : Science
Languages : en
Pages : 396
Book Description
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.

Central Regulation of Autonomic Functions
Author: Arthur D. Loewy
Publisher: Oxford University Press
ISBN: 0199763119
Category : Science
Languages : en
Pages : 406
Book Description
This unique text relates the dramatic advances of modern neurobiology to our understanding of the structure and function of the autonomic nervous system, providing a clear view of the central neuronal components involved in autonomic control. The scope is wide, ranging from anatomical pathways and molecular pharmacology to the perceptual qualities of autonomic sensation and their potential in modifying behavior. Essential background information is reviewed and the most recent research discussed in a readable, informative manner. The text is richly illustrated. The first six chapters offer a comprehensive review of the system's anatomy, physiology, and pharmacology, emphasizing the organization and control of the autonomic preganglionic neurons and the complexity of central pathways. Later chapters review the autonomic control of cardiovascular, sexual, urinary, endocrine, and other functions. Written by an international group of distinguished scientists, this work is a valuable resource for clinicians, scientists, and graduate students in the fields of anatomy, physiology, pharmacology, and neuroscience.

Respiratory Physiology of Vertebrates
Author: Göran E. Nilsson
Publisher: Cambridge University Press
ISBN: 1139485350
Category : Science
Languages : en
Pages : 351
Book Description
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.
