question 15 of 20
which is an age - related change of the hepatobiliary system?

• increased drug clearance capability
• enlarged liver
• decreased blood flow
• decreased prevalence of gallstones.

Explanation:

To determine the age - related change of the hepatobiliary system, we analyze each option:

• Option "Increased drug clearance capability": As people age, the liver's function to clear drugs usually decreases, not increases. So this is incorrect.
• Option "Enlarged liver": With aging, the liver generally shrinks rather than enlarges. So this is incorrect.
• Option "Decreased blood flow": Aging is associated with a reduction in hepatic blood flow. This is a correct age - related change of the hepatobiliary system.
• Option "Decreased prevalence of gallstones": The prevalence of gallstones increases with age, not decreases. So this is incorrect.

Answer:

C. Decreased blood flow
