Gas Exchange II: Ventilation and Perfusion and V/Q Ratios

Concept: Ventilation, Perfusion, V/Q Ratios


Concept: V/Q Changes in Lung Regions


Problem: A tumor growing in a bronchus grows so large that it completely obstructs the passage and blocks air flow. Which of the following describes the space downstream of the blocked bronchus and the resulting V/Q ratio in that area?


Problem: In a normal person standing upright, which of the following increase from the top to the bottom of the lung? (Choose all that apply.)
