Title: Chloride ions, Cl-, follow actively transported Na+ ions from the nephron into the blood. would you not expect? Post by: nzrodrigue on Sep 27, 2012 Chloride ions, Cl-, follow actively transported Na+ ions from the nephron into the blood. would you not expect the Cl- concentration to decrease as fluids are extracted along the nephron? What causes the discrepancy?
Title: Chloride ions, Cl-, follow actively transported Na+ ions from the nephron into the blood. would you Post by: oaklandowns on Sep 27, 2012 That as the water concentration decreases, the chlorine concentration increases because it's not diluted by the water (you know like when you're making up a standard solution, the concentration [moldm-3] depends on the amount of solute dissolved in the solvent)
Because the solution within the tubule has a lower concentration (thanks to osmosis) it causes Cl- to diffuse out of the tubule, the attraction to sodium of course helps... That's the only thing I could think of :S |
