在肾小管内流动着的液体是(  )

A.原尿

B.尿液

C.动脉血

D.静脉血

答案

尿液的形成过程是:当血液流经肾小球时,除了血细胞和大分子的蛋白质外,血浆中的一部分水、无机盐、葡萄糖和尿素等物质,都可以经过肾小球滤过到肾小囊内,形成原尿;当原尿流经肾小管时,其中对人体有用的物质,包括大部分水、全部葡萄糖和部分无机盐,被肾小管重新吸收,并且进入包绕在肾小管外面的毛细血管中,重新回到血液里;在肾小管重吸收的同时,肾小管上皮细胞将所产生的物质(如氨)分泌到肾小管的官腔中,与原尿中剩下的其他废物,如尿素、一部分水和无机盐等由肾小管流出,形成尿液.因此在肾小管内流动着的液体已经是尿液了.如图所示:
