Space Physiology: From Earth to Space and Back Again provides readers with new and authoritative information about current and important topics related to risks in space. The book covers translation of Earth-based physiology to astronaut health and Earth applications of space research. Topics include adaptations of various systems to space, including bone, microcirculation, microcirculation, skeletal and smooth muscles, headward fluid shifts as well as integrated countermeasures to maintain well-being and health in space. This is a volume in Elsevier's new series Hot Topics in Physiology, published in association with the International Union of Physiological Sciences (IUPS). It is an ideal reference for academics and researchers (space physiology and medicine, rehabilitation medicine, biochemistry and cell biology, molecular biology) at Undergrad, Masters, PhD, and Post-Doc levels.
