How much do you know about your lungs?
当我们提起肺脏，第一个想到的就是它是一个呼吸的器官。
人体通过肺脏从自然界吸入清气，呼出体内的浊气，使体内外的气体交换，从而保证了人体新陈代谢的正常进行。吸入的清气与脾的营养精微物质在肺脏相结合生成宗气，以推动血液运行。
在中医理论上，肺也主宣发与肃降。肺主宣发，指肺气具有发散、上升的生理功能。肺主肃降，指肺气具有收敛、下降的生理功能。 肺气的宣发和肃降相互配合，相互制约，维持呼吸运动、水液代谢的正常进行。当“肺气失宣”，可见鼻塞、喷嚏、恶寒、无汗、呼吸不畅、胸闷、喘咳等症状；当“肺失肃降”，可见呼吸短促、喘息、咳痰等症状。 此外，肺气宣降对于体内水液代谢主要体现在两个方面： 一是肺气宣发，可将津液和来自脾的营养精微物质布散于全身，调节汗液的排泄。二是肺气肃降，可将体内的水液向下输送至肾，以尿液的形式排出体外。 肺上通鼻子，外合皮毛，与自然界息息相通，易受外邪侵袭。因此，日常留意对肺的养护是防病的关键之一。 欲了解更多关于中医肺系统的知识及养生贴士，可期待我们之后为大家准备的文章与视频，或至本店向我们的中医师咨询详情。
