Question
Chapter 17, Problem 38RA
Summary Introduction
To review:
1. The xenobiotics and their excretion in the urine along with the carriers involved.
2. The interference of xenobiotics elimination with a medical treatment.
Introduction:
The renal system in the body is associated with the formation of urine, maintaining the fluid balance and the elimination of harmful substances from the blood. The renal system monitors the level of dissolved materials in the blood and excretes the materials that are unwanted, and present in an excess amount.

The renal handling of a novel drug is being studied. When the drug is present in the blood, it is filtered into the Bowman’s capsule and secreted via transport proteins in the renal tubules, but it is NOT reabsorbed. The lines on the following graph represent filtration, secretion and excretion rates of this drug at various plasma concentrations.
For the three lines shown (labeled A-C) identify which line represents filtration, which line represents secretion, and which line represents excretion
Explain how you determined this.
How are CFU (colony forming units) calculated in urine?
(Hint/comment: what is the volume in urine cultures)
lease answer the following questions:
Another patient has signs of glomerular capsule damage (damage to the filtration membrane) and now tests positive for proteins in her urine.
What effect, if any, might this have on NFP and why?
The same patient is showing signs of edema in her hands and feet (peripheral edema). What might be the explanation for this?
What effect might the presence of a kidney stone have on NFP? Explain why?
