Substance
Proximal Tubule
Loop of Henle
Distal Tubule and Collecting Duct
Hormonal Influences
Sodium
  • Passively enters the cell via ion channels or co-transporters in the apical membrane.
  • Is pumped out of the cell via the sodium/potassium ATPase in the basolateral membrane
  • Link to Article
Potassium
  • Potassium mainly moves across the membrane via the paracellular route.
  • It is then pumped into the cell in exchange for sodium via the sodium/potassium ATPase in the basolateral membrane
  • It then leaves the cell using a co-transporter with chlorine
  • Link to Article
Urea
Water
Glucose
  • It is reabsorbed using a co-transporter with sodium via secondary active transport
  • Link to Article
Protein
Calcium
  • Bulk reabsorption but not regulation of calcium occurs in the proximal tubule
  • Link to Article
H+ and HCO3-
Organic Acids and Bases
