No textbook about spaceflight life support systems can be written without a basic overview of physiology. After all, the life support system is what keeps astronauts alive. To fully understand the intricacies of these engineering systems, it is necessary to first understand the physiological systems. To that end, Chap. 2 delves into basic physiology, with some psychology thrown in. One aspect of physiology emphasized in this chapter is that we humans can only operate within very, very narrow environmental parameters. For example, a partial pressure that is too high or too low can cause all sorts of problems. Thus, human limitation represents a big challenge for life support system engineers. Another aspect highlighted is the adaptive timeline across physiological systems. Some systems, such as the fluid system, adapt to microgravity after 4–6 weeks, but other systems, such as the skeletal system, have no clinical horizon, so this is a good place to start.
