Question

what is the difference between sheep ureter vs human ureter

Answer 1

Sheep urinary system

Human Urinary system

Cross-sections of upper, middle, and lower ureteral segments from human autopsy specimens and sheep was evaluated after preparation with Masson's trichrome stain. The epithelium was remarkably consistent across all species of sheep, both morphologically and in terms of absolute size. The lamina propria was highly vascularized in the sheep, but the compactness varied with the overall ureteral dimensions. In the muscularis, the relative size and the percentage composed of smooth muscle differed widely with that of humans, as did the ratio of muscularis to lamina propria cross-sectional surface area. But histologically, the sheep ureter has almost similar structures to that of the humans.
