清晨,漫步于花間树下,人們都喜欢做几节深呼吸运动。做深呼吸运动有哪些好处呢? 平时,平靜的呼吸动作我們称为“平和呼吸”。一般成年人在一次平和呼吸中,呼出或吸入的气量約为500毫升,而真正与肺泡进行气体交換(肺泡排出二氧化碳,同时从外界气体中吸收氧)的沒有这么多。因为尚有“无效腔”中的气体不能与肺泡进行气体交換。 In the early morning, stroll under the tree between flowers, people like to do a few deep breathing exercises. What are the benefits of deep breathing exercises? Peaceful breathing is what we call “peaceful breathing.” In general, adults breathe or inhale about 500 milliliters of air in one breath. There is not so much gas exchange with the alveoli (alveolar exhalation of carbon dioxide and absorption of oxygen from the outside air). Because there is still gas in the “invalid cavity”, gas exchange with the alveoli is impossible.
