45. Uses a Na/K/Cl exchanger to move Na+ and Cl- from the epithelial cell into the interstitial fluid.
The ascending limb is largely impermeable to water. Na+, K+ and Cl− ions are reabsorbed by active transport. The mechanism of active transport is through Na+/K+/Cl− co-transporter as well as Na+/H+ exchanger. This active transport enables kidney to establish osmotic gradient that is essential for the kidney to concentrate the urine.
