Textbook Question
Chapter 20.2, Problem 5CC
Experiments suggest that there are peripheral osmoreceptors in the lumen of the upper digestive tract and in the hepatic portal vein [Fig. 14.1, p. 435]. What is the adaptive significance of osmoreceptors in these locations?

Cholestyramine is an anion-exchange resin used by clinicians to lower serum cholesterol in patients. This oral medication forms insoluble complexes with bile salts in theintestine, thus preventing their reabsorption. Explain themechanism by which cholestyramine lowers serum cholesterol levels.
