How do mammal kidneys differ from the kidneys of other vertebrates?
Wiki User
∙ 13y ago
Only mammalian kidneys have a renal pelvis (dilated beginning of the ureter) and renal pyramids (8 to 18 cone-shaped tissues in the renal medulla). The renal medulla (the innermost part of the kidney), and the renal cortex (surrounds the renal medulla) are more distinguishable in mammals than in other vertebrates.
