Introduction:
The ventilation-perfusion
The pressure of carbon dioxide and oxygen at the capillary end is same as the alveolar end in lungs, that is,
Answer to Problem 3RQ
Correct answer:
1, 2, 3, and 4
Explanation of Solution
Justification/ Explanation for the correct answer:
Option (d) is given that when the
Similarly, as the ventilation rate of the alveoli decreases, the oxygen pressure inside the alveoli also decreases. Thus, the
Explanation for the incorrect answer:
Option (a) is given that when the
Option (b) is given that when the
Option (c) is given that when the
Hence, options (a), (b), and (c) are incorrect.
The ventilation-perfusion rate differs throughout the lungs. The decrease in the

In 400 volunteers who took Maplex, 250 said they coughed less. Does this prove that Maplex is an effective anti-coughing drug? A. Not yet. We need to see whether the same percent of volunteers who took a placebo also report coughing B. There is no way to either prove or disprove that Maplex reduces coughing C. Yesarrow_forward
