This third volume in the ""Space Biology and Medicine"" series addresses the major issues concerning humans in space, such as metabolism, the immune system, neurosensory and sensory motor functions, gravitational biology, radiation, pharmacokinetics and much more. It is composed of two parts: ""Effects of Microgravity"" and ""Effects of Other Spaceflight Factors"". As in the previous two volumes, the contributing authors are experts in their respective fields. This book should appeal particularly to students majoring in biomedical and technical subjects who intend to specialize in space science, engineers developing life support systems, and physicians and scientists formulating medical specifications for habitability conditions onboard spacecraft and monitoring compliance with them. There are more than 285 figures and tables and 1100 references.
