Solution

The correct option is B $P o_{2}$ 95 mm Hg; $P c o_{2}$ 40 mm Hg
$P o_{2}$ in oxygenated blood (95 mm Hg) $> P o_{2}$ in body cells (40 mmHg) and $P c o_{2}$ in oxygenated blood is 40 mm Hg of $< P c o_{2}$ in body cells (45 mm Hg) during exchange of gases between blood and tissue. Therefore, in systematic arteries, $P o_{2}$ is 95 mm Hg and $P c o_{2}$ is 40 mm Hg.
