Description

Advances in Physiological Sciences, Volume 19: Gravitational Physiology covers the proceedings of the 28th International Congress of Physiological Sciences. The volume presents studies that tackle the biological concerns caused by the interactions between complex living organisms and altered gravitational field. The articles in the text are organized into parts, based on their main theme. The first part presents materials about the general problems when adapting to altered gravity system, such as physiological mechanisms of adaptation of mammals to weightlessness, and studies of biorhythms in biosatellite experiments. In the next part, the selection presents papers about metabolism and morphology that include stress metabolic aspects in space flight and the effect of spaceflight on human lymphocyte activation. The text also covers the function and structure of gravity-dependent systems, along with hypokinesia and immobilization. The book will be of great interest to health professionals involved in various space programs.
