Question
Chapter 20, Problem 14RQ
Summary Introduction
To determine: The two ways in which kidneys regulate the pH of plasma.
Introduction: Kidney plays an important role in regulating pH. The basic functional unit of the kidney is nephron. These nephrons have three major structures: proximal convoluted tubule, distal convoluted tubule, and loop of Henle. These structures help in the regulation of pH by altering the number of hydrogen ions.
Summary Introduction
To determine: The compounds which serve as urinary buffers.
Introduction: Urinary buffers are those molecules which change the pH of the urine. It is important to increase the pH of urine. It is regulated by altering the hydrogen ion concentration in the filtrate.

Describe the three processes involved in urine formation: filtration, secretion and reabsorption. Discuss the formula: E = F – R + S.
What is an example of a diagram that explains the core concept of flow down gradients in the urinary system/kidneys?
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.
