Answer to Question 1

ANS: B
These structures are lined with a ciliated mucosa that warms and humidifies inspired air and re-moves foreign particles from it. Air is not absorbed or cooled by the ciliated mucosal membrane. Gas exchange occurs in the alveoli.

Answer to Question 2

ANS: A
Hypertension in a 5-year-old is related to renal disease. Secondary hypertension in a 5-year-old is not usually related to a brain tumor, hypocalcemia, or hyponatremia.
