Abstract:
This study aimed to compare the renal structures and histological features of rabbits and guinea pigs. Methods: Anatomical dissection and histological examination were used to observe kidney and adrenal gland structures. For histological analysis, kidney tissues were collected, processed, and stained for microscopic evaluation. Glomerular size and renal tubule structures were measured. Findings: Rabbits have asymmetrically located kidneys, with the right kidney positioned ahead of the left, while guinea pig kidneys are aligned at the same level and closer to the midline. Guinea pigs' adrenal glands are attached to the kidneys, unlike rabbits. Histologically, guinea pigs have larger glomeruli, and while both species have similar renal capsules, their renal tubules are lined with cuboidal cells, with tubule diameters increasing toward the collecting tubes. Conclusion: The study identifies key anatomical and histological differences in the renal structures of rabbits and guinea pigs, particularly in kidney positioning, glomerular size, and adrenal gland relationships.
