Systems supporting human life and survival range from small items like oxygen masks or protective suits to the global biosphere. However, in a long run, the former ones cannot work without proper functioning of the latter. A consequence for biomedical research is the challenge to more fully understand, and to take into account, complex ecophysiological systems interdependencies. The development of life support systems (LSS) as used in manned flight significantly contribute to our understanding of life on a grand scale. A "medium-sized" materially closed LSS model is Biosphere 2, which completely recycles waste, provides clean air, potable water, and nutrient-dense food to a crew of 8 for basically unlimited time.
支持人类生命和生存的系统范围广泛，从小型物品如氧气面罩或防护服到全球生物圈。然而，从长远来看，前者若没有后者的正常运转便无法发挥作用。这给生物医学研究带来的一个后果是，要更全面地理解并考虑复杂的生态生理系统相互依存关系面临挑战。载人飞行中使用的生命支持系统（LSS）的发展极大地促进了我们对宏观生命的理解。一个“中型”物质封闭的LSS模型是生物圈2号，它能完全回收废物，为8名乘员提供清洁空气、饮用水和营养丰富的食物，基本可维持无限时长。
