Concept #1: Ventilation, Perfusion, V/Q Ratios
Concept #2: V/Q Changes in Lung Regions
Practice: 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?
Practice: In a normal person standing upright, which of the following increase from the top to the bottom of the lung? (Choose all that apply.)
