The ability to form concentrated urine depends on the functions of the nephron loop (loop of Henle) and the collecting duct.
Each kidney nephron has a long, U-shaped section of tubule called the loop of Henle that carries urine. It can be discovered in the kidneys of mammals, reptiles, and birds. Utilizing the concept of "countercurrent multiplication," the main purpose of the Henle loops and the thick ascending limb of the distal tubule is to concentrate urine.
Nephrons are physically connected to a minor calyx or the renal pelvis by a network of tubules and ducts that make up the kidney's collecting duct system. Aldosterone and vasopressin regulate mechanisms in the collecting duct system, the final component of the nephron, that contribute to electrolyte and fluid balance through reabsorption and excretion (antidiuretic hormone).
