【摘要】 用6只绵羊的左右肾进行了扫描电镜观察.结果显示:绵羊肾小球血管的外部构筑可分为球型和混合型.极少数肾小球上有两支出球小动脉,在两支出球小动脉之间偶见血管袢,有的出球小动脉有分支.在肾小球的血管极处,肾小球旁器内毛细血管网的网孔小且密集.呈三角形或不规则分布.肾小球入球小动脉入球后分为3～4条二级动脉组成小叶,每一小叶内又存在亚小叶循环单位.更多还原

【Abstract】 The kidneys of six sheeps were injected through the renal artery with ABS and the specimens were studied by scanning electronic microscopy(SEM). Under the SEM . renal glomeruli could be divided into spherical and mixed glomeruli, and anatomoses between the efferent vessels were observed. The efferent arterioles had many branches. The diameter of the meshes of the copillary network of the juxtaglomerular apparatus was smaller than that of the vessels themselves. There were some sublobular microcirulatary units in lobules.更多还原
