SOLVED:The diagram models the countercurrent exchange mechanism within the loop of Henle. The numbers within the loop show the osmolarity of the filtrate, while the numbers between the two loops indicate the osmolarity of the interstitial fluid within the kidney tissue. What would happen to the osmolarity of the interstitial fluid if water could not exit the descending limb? a. Osmolarity of the interstitial fluid would increase. b. Osmolarity of the interstitial fluid would decrease. c. There w
