为了讨论慢性支气管炎这个病,我们用示意图说明支气管和肺泡的正常结构,慢性支气管炎的病变发生、发展的情况和对心脏的影响,最后讨论中医对慢性支气管炎的认识。一、呼吸系统的结构和主要功能呼吸系统包括:鼻腔→咽部→喉头→气管→支气管→细支气管→呼吸性支气管→肺泡导管→肺泡囊→肺泡。从鼻腔到细支气管是传导部,从呼吸性支气管到肺泡为呼吸部,所以呼吸系统是由传导部和呼吸部组成(图一)。小支气管壁由粘膜、粘膜下层、软骨和纤维膜等四部分构成(图二)。大气的温度是或高或低的,有时可以在零度以 In order to discuss the chronic bronchitis disease, we use the schematic diagram of the normal structure of the bronchi and alveoli, the occurrence of chronic bronchitis lesions, the development of the situation and the impact on the heart, and finally discuss the TCM understanding of chronic bronchitis. First, the structure and main respiratory system Respiratory system include: nasal → pharynx → larynx → trachea → bronchus → bronchioles → bronchial respiratory tract → alveolar duct → alveolar sac → alveolar. From the nasal cavity to the bronchioles is the conduction part, from the respiratory bronchi to the alveoli as the respiratory department, so the respiratory system is composed of the Department of conduction and respiratory (Figure 1). Small bronchial wall mucosa, submucosa, cartilage and fibrous membrane composed of four parts (Figure II). The temperature of the atmosphere is either high or low, sometimes at zero degrees
