Urine concentrations in the spaces of the sheep renal pelvis
1Institute of Animal Physiology, Slovak Academy of Sciences, Kosice, Slovak Republic.
Abstract:
Urine concentrations were measured in samples from the ureter, the pelvic cavity, close to the tip of the papilla, and from the most proximal part of the fornices of sheep kidneys. It was found that the concentration of urea, the osmolality, and the urine-to-plasma ratios of inulin, urea and the osmolality were higher in the ureter than in the pelvic cavity. The same parameters were found to be higher in the pelvic cavity than in the fornices except for the urea concentration which was unchanged. The results of this study revealed the various concentrations of urine in the ureter, the pelvic cavity and the proximal part of fornices of sheep kidney.
