对于哺乳动物，每次吸气都将富氧空气带进肺中被称为肺泡的“死胡同”。这些在肺泡中循环的空气通过与肺毛细血管的血液进行气体交换，输进氧气并带走血液中的二氧化碳。
Air circulating through these sacs transfers oxygen into the bloodstream that picks up the blood's carbon dioxide waste.
但正是肺的底部含有温度最高、血流量最大的血管，最频繁的气体交换在这里进行，将氧气运送到血液中。
Yet it's the bottom section of the lungs that contains the warmest and wettest blood vessels - the most efficient for gas exchange and moving oxygen into the blood.
呼吸系统的主要功用是提供空气到肺的通路及气体交换的场所。
The main function of the respiratory system is to provide passages and room for gaseous exchange.
联合使用靶向性氙生物大分子探测器，我们应该可以研究肺中的气体交换，探测最早阶段的癌细胞。
Used in combination with a target-specific xenon biomolecular sensor, we should be able to study the gas-exchange in the lung and detect cancerous cells at their earliest stage of development.
肺气管树是人体肺毛细血管与大气之间进行气体交换的通道。
Lung airway tree is the gas transport channels between pulmonary capillary vessel and atmosphere.
结论罗红霉素能改善大鼠急性肺损伤时气体交换能力，调节肺部细胞因子，对内毒素诱导的急性肺损伤有保护作用。
CONCLUSION Roxithromycin has a protective effect on rat acute lung injury induced by LPS through regulating cytokines, improving gas exchange ability, and inhibiting lung permeability.
布洛芬抑制前列腺素的生成，并通过增强缺氧性肺血管收缩反应而改善了肺损伤时的气体交换。
