Here's a breakdown:
* Renal Pyramids: These are cone-shaped structures within the kidney that contain the collecting ducts, which carry urine from the nephrons (the functional units of the kidney) to the renal pelvis.
* Renal Papillae: These are the pointed tips of the renal pyramids that project into the renal pelvis. They are responsible for releasing urine into the renal pelvis.
While the specific number and appearance of renal pyramids and papillae may vary slightly between species, cats definitely possess these structures.
