4 True/False Questions 1) If the GFR is too low, needed substances may pass so quickly through the renal tubules that they are not absorbed and instead are lost in the urine. Answer: FALSE Diff: 2 Page Ref: 972 2) In the kidneys, the countercurrent mechanism involves the interaction between the flow of filtrate through the loop of Henle of the juxtamedullary nephrons (the countercurrent multiplier) and the flow of blood through the limbs of adjacent blood vessels (the countercurrent exchanger). This relationship establishes and maintains an osmotic gradient extending from the cortex through the depths of the medulla that allows the kidneys to vary urine concentration dramatically. Answer: TRUE Diff: 3 Page Ref: 979-982 3) The ureter transports urine from the kidney to the urinary bladder. Answer:
