About this work
Description
A cinematographic study of the movements of the ureter in an anaesthetised rabbit. The left ureter, left kidney and bladder are first exposed by laparotomy; the urine is then darkened by injecting a dye (indigo carmine) into an ear vein, so that its passage along the ureter can be readily observed. Movements of the ureter are then recorded at three different camera speeds - normal, 3 times normal speed and slowed down 2 1/2 times. High speed photography shows the shape of the urine moiety. 1 segment.

Segment 1 The intertitles describe the ureter and its purpose. The left kidney, left ureter and bladder are exposed by laparotomy in an anaesthetised rabbit. The passage of normal urine along the ureter is shown. The rabbit is injected with indigo-carmine which is excreted in the urine, and so darkens the urine. The rate of passage of the urine is measured. Camera speed is adjusted for further study to three times faster and then 2 1/2 times slower. The dyed urine causes an apparent darkening of the bladder wall. The movements are repeated in close up, first at normal speed and then with faster and slower camera speeds. The shape of the urine moieties is determined by electronic flash photography. Time start: 00:00:00:00 Time end: 00:06:20:17 Length: 00:06:20:17
