【摘要】 为了了解红腹锦鸡(Chroysolophus pictus)肺的微细结构和微血管构筑特征,为呼吸生物学研究提供形态学依据,用组织学方法和微血管铸型技术在光镜和扫描电镜下观察研究了红腹锦鸡肺的组织结构与微血管构筑情况。结果表明,红腹锦鸡肺主要由各级支气管构成,从三级支气管上呈辅射状分出许多呼吸毛细管(微气管),并相互吻合成网状,呼吸毛细管外面包围有丰富的毛细血管;红腹锦鸡肺毛细血管垂直围绕在各微气管外,并相互吻合成密集的立体微血管网;毛细血管管径4.5~7.0μm,微气管直径11~50μm。并对肺微血管构筑情况与呼吸效率的关系作了探讨。更多还原

【Abstract】 Using light microscopy and scanning electron microscopy we observed the pulmonary tissue structure and microvasculature of the Chroysolophus pictus by histological method and microvascular casting technique.Results showed that the lung of C.pictus consists of bronchi in three levels.Many breathing capillaries(minute trachea) irridated from the third level’s bronchi,forming anastomosed reticulation with each other.There were rich pulmonary capillaries around minute trachea.They vertically ranked around the minute trachea and anastomosed mutually to form a stereoscopic microvascular network.The diameter of the capillary is 4.5-7.0?μm,and the diameter of the minute tracheal is 11-50?μm.In addition,the relationship between the microvasculature architecture of the lung and respiratory rate was also discussed.更多还原
