collecting duct of renal tubule 肾小管集合管 BTO:0000761 CALOHA:TS-0860 EMAPA:28407 EV:0100391 FMA:15628 GAID:434 MA:0000371 MESH:D007685 Renal duct that collects the output from renal tubules.[TAO] TAO:0005294 The collecting duct is a portion of the nephron through which water flows, moving passively down its concentration gradient UBERON:0001232 ZFA:0005294 arcuate renal tubule collecting duct collecting duct system collecting tubule in ISBN10:0073040584 (Vertebrates, Kardong), the nephron is adjacent to the collecting tubule, consistent with FMA, but not GO. Wikipedia says: Many sources include the connecting tubule as part of the collecting duct system. However, the embryological origin is more similar to the nephron than it is to the rest of the collecting duct (which derives from the ureteric bud), and other sources therefore classify the connecting tubule with the nephron junctional tube kidney collecting duct kidney collecting tubule renal collecting tubule tubulus renalis arcuatus tubulus renalis colligens uberon ureteric tree 在ISBN10:0073040584(脊椎动物，Kardong)中，肾单位与集合小管相邻，与FMA一致，但不与GO一致。Wikipedia说明：许多来源包括作为收集管道系统的一部分的连接细管。然而，胚胎学起源与肾单位更类似甚于其与集合管的其余部分(其源自输尿管芽)，因此其它来源将连接小管与肾单位分类。 弓形肾小管 接合管 肾弓形小管 肾管收集肾小管的输出物。[TAO] 肾集合小管(kidney collecting tubule) 肾集合小管(tubulus renalis colligens) 肾集合管(kidney collecting duct) 肾集合管(renal collecting tubule) 输尿管树 集合小管 集合管 集合管是肾元的一部分，流经其中的水，沿着它的浓度梯度移动。 集合管道系统 excretory tube 排泄管
