Chambers Of The Heart

Thousands of years ago, Polynesian voyagers discovered and settled Nanumea atoll, a tiny cluster of coral islets in the middle of the Pacific Ocean. The community prospered, first evolving into a traditional culture finely tuned to the atolls limited environment and then weathering new changes imposed by missionaries, colonial officials, and Westernization itself. Now one of eight separate island communities comprising the modern Pacific nation of Tuvalu, Nanumea faces new challenges: rising sea levels, globalization, and massive social and economic changes. Using personal stories that evoke the difficulties and excitement of fieldwork, Keith and Anne Chambers draw on more than twenty-five years of ethnographic research in Nanumea to craft an engaging account of Nanumean culture and social organization. Readers will come to appreciate how the communitys intense sharing obligations, service-oriented chieftainship, and a flexible system of extensive kinship reckoning define a lifestyle that differs fundamentally from modern Western society.

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 Studies in Physiology series provides a concise introduction to developments in complex areas of physiology for a wide audience. Published on behalf of the Physiology Society, Cardiovascular Regulation provides an up-to-date account of our current understanding of the control of the cardiovascular system that is not covered by existing textbooks. Both students and lecturers of cardiovascular and exercise physiology, medicine, dentistry and biomedical sciences will find this book informative and easy to read. Each chapter has numerous summary boxes. 'Essential reading' suggestions provide additional reading for undergraduates and the suggestions for 'Further reading' cover the subject to postgraduate level.

One of the most time-consuming tasks in clinical medicine is seeking the opinions of specialist colleagues. There is a pressure not only to make referrals appropriate but also to summarize the case in the language of the specialist. This book explains basic physiologic and pathophysiologic mechanisms of cardiovascular disease in a straightforward manner, gives guidelines as to when referral is appropriate, and, uniquely, explains what the specialist is likely to do. It is ideal for any hospital doctor, generalist, or even senior medical student who may need a cardiology opinion, or for that ma.

Research centering on blood flow in the heart continues to hold an important position, especially since a better understanding of the subject may help reduce the incidence of coronary arterial disease and heart attacks. This book summarizes recent advances in the field; it is the product of fruitful cooperation among international scientists who met in Japan in May, 1990 to discuss the regulation of coronary blood flow.

​There is an evident practice gap in education of general adult cardiologists on long-term management of congenital heart disease (CHD). The goal of this book is to help general cardiologists, but also pediatricians and related care providers in the management and diagnosis of adult CHD. Adult Congenital Heart Disease in Clinical Practice provides clear, practical advice on adult CHD for the busy fellow, resident and practicing clinician. It includes training and revision material to assist learning and is formatted in such a way as to provide short, concise content designed for easy recall of salient facts.

“This book is a reflection of a warrior putting into practice all that she has learned, the moment when knowledge turns into wisdom, in order to heal a heart that is not afraid to love.” — Don Miguel Ruiz Jr, author of The Mastery of Self & The Five Levels of Attachment In this continuation of the Warrior Goddess path, author HeatherAsh Amara shares a revolutionary new method to help you reconnect with your sense of authenticity and power. Too often we allow old narratives—about past failures, broken relationships, or damaging experiences—to define us, depleting our joy, limiting our passion, and whispering the poisonous lie that we are not enough. The Warrior Heart Practice is a revolutionary new method that will help you reevaluate those well-worn narratives and shift your thinking and intentions in a new, empowered way. Based on the four divisions of the heart, the practice leads you forward through the four chambers of experience—Feeling, Story, Truth, Intent—gently questioning your own assumptions along the way, and then back through the chambers in the reverse, so that you emerge armed with a clear understanding of your situation and a new sense of purpose and power. For those who have loved and lived Warrior Goddess Training and readers who are searching for a new freedom, The Warrior Heart Practice offers an inner revolution and a new path towards freedom.
