Urine is concentrated a) in the ureters. b) by active secretion in the loop of Henle. c) by facilitated diffu sion in the collecting ducts. d) by reabsorption in the proximal tubule.
Urine is concentrated byc) facilitated diffusion in the collecting ducts.
The collecting duct concentrates it by water reabsorption through facilitated diffusion when ADH is present.The permeability of the collecting ducts for water leads to a concentration of the urine up to the fivefold osmolarity of the plasma.The permeability of the collecting ducts is regulated with ADH.

Urine exits the kidneys through the: Bladder Urethra Ureters Collecting ducts Filtration of blood in the kidney nephron begins in the: Loop of Henle Proximal convoluted tubule Bowman's Capsule Distal convoluted tubule Most aquatic animals secrete nitrogenous wastes in the form of ____, but land animals convert this into other Chemicals that are less toxic. Urea Uric acid Ammonia Proteins When fats are digested: their breakdown products are absorbed into the bloodstream from the vill of the...
