慢性气管炎、肺气肿、肺原性心脏病都是常见病,它们都严重影响劳动人民的身体健康,甚至威胁生命。这三种病的关系很密切:慢性气管炎往往伴有肺气肿,肺气肿病人有不少最后发展成肺原性心脏病。这里我们来谈谈他们的因果关系和防治措施。从气管炎到肺气肿气管分成左右支气管,支气管象树枝样再反复分支,越分越细,最后与肺泡管和肺泡相通,就象一串串的葡萄。每一细支气管和它所属的肺泡构成一个肺小叶,许多小叶
Chronic bronchitis, emphysema and pulmonary heart disease are common diseases, all of which seriously affect the health of the working people and even threaten life. The relationship between these three diseases is very close: Chronic bronchitis is often accompanied by emphysema, emphysema, many patients eventually developed into pulmonary heart disease. Here we talk about their causal relationship and prevention and control measures. From bronchitis to emphysema trachea divided into bronchus, bronchial branches like repeated branches, the more sub-fine, and finally connected with the alveolar and alveolar, like a bunch of grapes. Each bronchiole and its alveoli form a lobule, many of the lobules
