Answer to Question 1

ANS: C
The partial pressure of carbon dioxide (PCO2) is highest in the cells (approximately 60 mm Hg).

Answer to Question 2

ANS: D
PACO2 varies directly with the body's production of carbon dioxide (CO2) and inversely with alveolar ventilation (VA). Under normal conditions it is maintained at approximately 35 to 45 mm Hg.
