[The morphofunctional basis for the effect of respiratory movements on urine production and the urinary excretory functions of the kidneys in the turtle].
Influence of respiratory movements on urine formation and excretory function of turtle kidneys are substantiated in the present research. It was performed in 55 mature male steppe turtles using injection, histological, histochemical and experimental methods. Following animal transfer to regulated respiration by means of tracheostome application the oscillations of tension were monitored in ureter lumen and cavities surrounding kidney as well as change in shape and size of initial widened regions of excretory tubules as a response to strong inspiration and expiration. These structures were shown to affect uric acid and mucin secretion and urine passage in ureter tributaries and ureters.
