本文所述是近年来进一步认识的肺非呼吸功能,包括代谢、防御、免疫及内分泌等功能.一、肺的代谢功能肺是一个重要的呼吸器官,而今更明确肺具有活跃的代谢功能,肺更是一个主要代谢器官,这与肺的功能和结构密切相关.1.肺Ⅱ型细胞是肺泡表面活性物质的主要合成、贮存和分泌场所,当窒息缺氧或肺循环灌流不足 This article describes the lung non-respiratory function in recent years to further understand, including metabolism, defense, immune and endocrine functions.First, the lungs of the lung function is an important respiratory organ, and now more clearly the lungs with active metabolic function, lung Is a major metabolic organ, which is closely related to the function and structure of the lungs.1 Lung type Ⅱ cells are the main sites for the synthesis, storage and secretion of alveolar surfactant. When asphyxia or pulmonary perfusion is inadequate
