Nephron
Cats have two kidneys, and each kidney contains thousands of microscopic units called nephrons. These nephrons consist of a renal corpuscle, convoluted tubules, and a collecting duct, but they do not form pyramids. Pyramids are specific structures found in the medulla of the kidneys in animals like humans.
Peritubular fluid refers specifically to the fluid found in the renal tubules of the kidney, while interstitial fluid is found in the spaces surrounding cells throughout the body, including the kidney. While they both play a role in transporting substances and maintaining homeostasis, they are located in different anatomical compartments.
The ureter is found between the kidney and the urinary bladder. It is responsible for carrying urine from the kidney to the bladder.

Ibuprofen is primarily excreted through the kidneys. After metabolism in the liver, it is eliminated from the body mainly as metabolites in the urine, with a small percentage excreted as unchanged drug. Additionally, trace amounts can also be found in bile and feces. This renal excretion is why monitoring kidney function is important in patients taking ibuprofen, especially those with pre-existing kidney issues.
