Question

During the exchange of gases between lung alveoli and pulmonary capillaries, if the partial pressure of oxygen in a aveolarcapillaries is $95\, m \,m \,Hg$ and the partislpressure of $CO_{2}$ is $45\, mm \,Hg$ in deoxygenated blood. Based on this identify the correct statement

• A. The partial pressure of oxygen will be highest, i.e., $104\, mm\, Hg$ in alveoli
• B. The partial pressure of nitrogen will remain same in both blood and alveoli
• C. The partial pressure of $CO_{2}$ is less in pulmonary veins as compared to pulmonary arteries
• D. All of these

Answer 1

Answer: (D)

Correct answer is (d) All of these
