Could someone correct/help explain? Thanks!

QUESTION 11 The following describes a positive feedback mechanism, called the countercurrent multiplier system, which results in a hypertonic renal medudlse ascending or descending for each blank. The NaCl pumped into the interstitial fluid by the ascending limb causes the filtrate in the limb to become increasingly concentrated. This occurs because of osmosis of water out of the descending ascending limb allows the cells of the ascending drawing even more water out of the descending limbs into the surrounding capillaries. The increasingly concentrated fluid entering the ascending limb to pump out an increasing concentration of NaCl, thereby limb

Explanation / Answer

The NaCl pumped into the interstitial fluid by the ascending limb causes the fluid in the ascending limb increasingly concentrated. This occurs beacause of osmosis of water from the descending limb into the surrounding capillaries. The increasingly concentrated fluid entering the ascending limb allows the cells of the ascending limb to pump out an increasing concentration of NaCl, thereby drawing even more water out of the descending limb.
