Which of the following statements concerning the nephron loop and its function is FALSE?
Sodium and chloride are pumped out of the thin descending limb of the nephron loop. The nephron loop reabsorbs roughly half the water and two-thirds of the sodium and chloride ions in the tubular fluid. Water moves by osmosis out of the descending limb of the nephron loop. The pumping of sodium and chloride from the nephron loop elevates the osmotic concentration in the peritubular fluid.
