Regulation of Tissue Oxygenation, Second Edition


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.







Body and Blood


Book Description

The best Indian writer of our times -- MOHAMMED HANIF When Midhun is injured in a hit-and-run incident, no one can anticipate that the minor scrapes and wounds he has sustained will suddenly turn fatal. But that is exactly what happens, and after his death, his organs are donated and end up saving several lives. Soon, however, his friends Rithu and Ragesh and his lover Sandhya begin to suspect there is more to the story than meets the eye. As they delve deeper into the chain of events and the people behind the religious fellowship they are all a part of, they discover that answers are hard to come by, justice elusive and closure next to impossible...Following the lives of men and women caught in a web of criminally orchestrated accidents and medically induced comas, Benyamin's latest novel Body and Blood is by turns introspective and thrilling -- a meditation on faith and God that also holds up a mirror to the power and corruption of organized religion.

Body Work


Book Description

Are scientific 'facts' about body image enough to define conceptions of normality? Reassessing Experimental Psychology from a critical perspective, Sylvia Blood demonstrates how its research into Body Image can be misused and prone to misuse. Classifying women who experience distress and anxiety with food, eating and body size as suffering 'body image disturbance' or 'body image dissatisfaction', it can reproduce dominant assumptions about language, meaning and subjectivity. Experimental psychology's discourse about body image has recently become more widely influential, becoming popularised through domains such as women’s magazines, in which psychological experts provide 'facts' about women's 'body image problems', and offer advice and psychological treatments. With acute cross-disciplinary awareness Body Work: The Social Construction of Women's Body Image exposes the assumptions at work in the methods and status of experimental approaches. Penetrating beyond the usual dichotomy between experimental and popular psychology, this book illuminates some of the ways in which women's magazines have embraced experimental psychology's treatment of the issue. Drawing on her experience in Clinical Psychology, Sylvia Blood highlights the damaging effects of uncritically experimental views of body image. She goes on to elaborate not only an alternative model of discursive construction but also the implications of such a theory for clinical practice. Merging theory and clinical experience, Sylvia Blood exposes the fallacies about women’s bodies that underpin experimental psychology's body image research. She demonstrates the dangerous consequences of these fallacies being accepted as truths in popular texts and in the talk of 'everyday' women.




Circulation of the Blood


Book Description

Capturing the real spirit of creativity in physiology, this book explores the personal elements involved in scientific discovery. Circulation of the Blood is the story of the people and achievements that have changed the way we've come to view the human body. The authors, renowned for their extensive experience in the field, examine the heritage of creative genius involved in physiology and trace the historical development of ideas relating to various aspects of circulation of the blood. Their comprehensive coverage goes from the early discoveries of the Greeks and Romans up to modern times.




HIV and the Blood Supply


Book Description

During the early years of the AIDS epidemic, thousands of Americans became infected with HIV through the nation's blood supply. Because little reliable information existed at the time AIDS first began showing up in hemophiliacs and in others who had received transfusions, experts disagreed about whether blood and blood products could transmit the disease. During this period of great uncertainty, decision-making regarding the blood supply became increasingly difficult and fraught with risk. This volume provides a balanced inquiry into the blood safety controversy, which involves private sexual practices, personal tragedy for the victims of HIV/AIDS, and public confidence in America's blood services system. The book focuses on critical decisions as information about the danger to the blood supply emerged. The committee draws conclusions about what was doneâ€"and recommends what should be done to produce better outcomes in the face of future threats to blood safety. The committee frames its analysis around four critical area: Product treatmentâ€"Could effective methods for inactivating HIV in blood have been introduced sooner? Donor screening and referralâ€"including a review of screening to exlude high-risk individuals. Regulations and recall of contaminated bloodâ€"analyzing decisions by federal agencies and the private sector. Risk communicationâ€"examining whether infections could have been averted by better communication of the risks.
