David Weiner, M.D. Professor of Medicine and Physiology University of Florida College of Medicine Basic principles Proximal tubule Majority of transport Transport is Na + -linked Loop of Henle Thin descending limb, H 2 O transport for counter-current multiplication Thick ascending limb Moderate ion transport capacity Major site for regulation of Ca +2 transport Distal convoluted tubule NaCl reabsorption, no H 2 O transport Generates dilute urine Collecting duct Quantitatively less transport, but highly regulated Major site of regulated H 2 O, K + , titratable acid and ammonia transport Specialized cells transport each molecule independently, or almost so Proximal tubule Lumen Peritubular Na + K + ↓Na + i ↑K + i K + K + -70 mV 140 mM Na + 4 mM K
