Question

Read the given statements.
(A) The solubility of ${CO}_2$ is almost equal to $O_2$
(B) ${PCO}_2$ in pulmonary vein is 40 mm Hg
(C) Alveoli are the primary site of transport of gases
(D) Alveolar will is one-celled thick

• A. A-Correct, B-Correct, C-Incorrect D-Correct
• B. A-Incorrect B-Correct C-Correct ,D-correct
• C. A-Incorrect , B-Incorrect, C-Correct, D-Correct
• D. A-Correct, B-Incorrect , C-Correct D-Incorrect

Answer 1

The correct option is A A-Correct, B-Correct, C-Incorrect D-Correct

Carbon dioxide is more soluble in blood than oxygen.

$PC{O}_2$ in pulmonary vein is 40 mm of Hg.

Alveoli is provides the surface for exchange of gases.

Exchange of gases is possible because the alveolar wall is one celled thick.

So the correct option is ' A- Incorrect, B - Correct, C- Correct, D - Correct '.
