Comparing Solutes in the Plasma, Nephron, and Urine ficropipettes were used to draw fluids from the Bowman's apsule, the glomerulus, the loop of Henle, and the collecting uct. Solutes in the fluids were measured. The resulting data re displayed in the table below. Some of the data were not ken, as indicated in Table 1. analysis (a) Which of the solutes was not filtered into the nephron? Explain your answer. (b) The test for glucose was not completed for the sample taken from the glomerulus. Predict whether glucose would be found in the glomerulus. Provide reasons for your prediction. able 1 Solute Bowman's c capsule protein 0 urea 0.05 glucose 0.10 chloride 0.37 ammonia 0,0001 substance X 0 Questioning Hypothesizing Predicting O Planning Q Conducting O Recording Analyzing O Evaluating Communicating (c) Why do urea and ammonia levels increase after filtration occurs? (d) 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? (e) Is it correct to say that veins carry blood with high concentrations of waste products and arteries carry blood with high concentrations of nutrients? Explain. (f) Compare the blood found in a renal artery and a renal vein with respect to urea and glucose.
