摘要

20年前,Bodil Schmidt-Nielsen和Bruce Graves在一个非凡的视频中记录了肾盂有节奏的收缩,直观地展示了蠕动波是如何使乳头变空的,以及随后的弹性反冲是如何将水从集合管吸引到栓系打开的上升直血管的。因此,周期性流体静力梯度产生轴向渗透梯度。这篇评论概述了视频,并提供了从原始磁带数字化的数字和场景的链接。

The renal pelvis: machinery that concentrates urine in the papilla.

Two decades ago, Bodil Schmidt-Nielsen and Bruce Graves documented the rhythmic contractions of the renal pelvis in a remarkable video, visually demonstrating how peristaltic waves empty the papilla and how the subsequent elastic recoil draws water from the collecting duct and into the tethered-open ascending vasa recta. Thus a periodic hydrostatic gradient generates an axial osmotic gradient. This review recapitulates the video and offers a link to figures and scenes digitized from the original tape.
