Body fluid regulation is pivotal to human health and is served by extensive clinical and pre-clinical science. By combining modern advances with previous findings in the field, this book presents a comprehensive treatment of major experiments, theories, and new advances in the field of body fluid regulation, thirst, and drinking. It features the main integrative brain mechanisms for fluid regulation, the development of such systems, fluid balance during heat and exercise, aging and clinical disorders, and comparative aspects of fluid regulation. The volume focuses on mammalian thirst or drinking behaviour alongside relevant aspects of the physiology of fluid balance. The principal fluid compartments and their regulation by both intakes and losses are highlighted, using both human and animal studies to illustrate the main concepts.

A timely symposium entitled Body-Fluid Homeostasis: Transduction and Integration was held at Araraquara, São Paulo, Brazil in 2011. This meeting was convened as an official satellite of a joint gathering of the International Society for Autonomic Neuroscience (ISAN) and the American Autonomic Society (AAS) held in Buzios, Rio de Janeiro. Broad international participation at this event generated stimulating discussion among the invited speakers, leading to the publication of Neurobiology of Body Fluid Homeostasis: Transduction and Integration. Drawn from the proceedings and filled with rich examples of integrative neurobiology and regulatory physiology, this volume: Provides updated research using human and animal models for the control of bodily fluids, thirst, and salt appetite Explores neural and endocrine control of body fluid balance, arterial pressure, thermoregulation, and ingestive behavior Discusses recent developments in molecular genetics, cell biology, and behavioral plasticity Reviews key aspects of brain serotonin and steroid and peptide control of fluid consumption and arterial pressure The book highlights research conducted by leading scientists on signal transduction and sensory afferent mechanisms, molecular genetics, perinatal and adult long-term influences on regulation, central neural integrative circuitry, and autonomic/neuroendocrine effector systems. The findings discussed by the learned contributors are relevant for a basic understanding of disorders such as heat injury, hypertension, and excess salt intake. A unique reference on the neurobiology of body fluid homeostasis, this volume is certain to fuel additional research and stimulate further debate on the topic.

Body Fluid Balance: Exercise and Sport brings you the latest thinking on important topics in this dynamic research area. The authors of this authoritative compendium provide enlightening data and unique perspectives that will stimulate other investigators and supply independent analyses for practitioners and educators. The book is efficiently organized into three sections: Section one addresses control of body fluid during exercise. Topics range from basic thirst mechanisms to specific organ control. Section two discusses environmental influences on body fluid balance, including heat, cold, altitude, and immersion. Section three describes special considerations affecting body fluid balance during exercise, such as age, gender, physical performance, and clinical complications. Each chapter presents historical perspectives, critical experiments, appropriate analyses, and pertinent conclusions. Nowhere else will you find the information you need in such an easy-to-follow, convenient format.

Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate The Dietary Reference Intakes (DRIs) are quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. This new report, the sixth in a series of reports presenting dietary reference values for the intakes of nutrients by Americans and Canadians, establishes nutrient recommendations on water, potassium, and salt for health maintenance and the reduction of chronic disease risk. Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate discusses in detail the role of water, potassium, salt, chloride, and sulfate in human physiology and health. The major findings in this book include the establishment of Adequate Intakes for total water (drinking water, beverages, and food), potassium, sodium, and chloride and the establishment of Tolerable Upper Intake levels for sodium and chloride. The book makes research recommendations for information needed to advance the understanding of human requirements for water and electrolytes, as well as adverse effects associated with the intake of excessive amounts of water, sodium, chloride, potassium, and sulfate. This book will be an invaluable reference for nutritionists, nutrition researchers, and food manufacturers.

The brain's three sensory circumventricular organs, the subfornical organ, organum vasculosum of the lamina terminalis and the area postrema lack a blood brain barrier and are the only regions in the brain in which neurons are exposed to the chemical environment of the systemic circulation. Therefore they are ideally placed to monitor the changes in osmotic, ionic and hormonal composition of the blood. This book describes their - General structure and relationship to the cerebral ventricles - Regional subdivisions - Vasculature and barrier properties - Neurons, glia and ependymal cells - Receptors, neurotransmitters, neuropeptides and enzymes - Neuroanatomical connections - Functions
