Concerning lung vessel resistance: a- Total resistance increases from low to high lung volumes. b- In extra-alveolar vessels, it is higher at maximal inspiratory volume than at FRC. c- In alveolar vessels, it decreases with increasing volumes. d- None of the above.

Step 1
Step 1: Total resistance in the lung vessels is determined by both extra-alveolar vessels (outside the alveoli) and alveolar vessels (within the alveoli). Show more…

In emphysema, the alveolar walls are destroyed, decreasing the recoil of the lung tissue. Which of the following changes may be seen in a patient with emphysema? (A) Increased residual volume (B) Decreased total lung capacity (C) Increased blood concentration of oxygen (D) Decreased blood concentration of carbon dioxide
Restrictive airway diseases __________________ . a. increase the compliance of the lung b. decrease the compliance of the lung c. increase the lung volume d. decrease the work of breathing
A patient is suffering from an allergic reaction that causes his airways to swell up. How would this most likely affect resistance of the respiratory system, and why? a. Resistance decreases because it will be harder for air to flow through the airways. b. Resistance decreases because the airways are more compliant. c. Resistance increases because it will be harder for air to flow through the airways. d. Resistance increases because the airways are more compliant.
