2018 Breathing and Exchange of GasesDisorders of the respiratory system Easy Question 26 of 53 in Breathing and Exchange of Gases

Which of the following options correctly represents the lung conditions in asthma and emphysema, respectively?

A Increased respiratory surface; Inflammation of bronchioles
B Increased number of bronchioles; Increased respiratory surface
C Inflammation of bronchioles; Decreased respiratory surface
D Decreased respiratory surface; Inflammation of bronchioles

The answer is C.

Solution

Asthma = bronchiole inflammation; emphysema = reduced alveolar surface.

Asthma is a difficulty in breathing causing wheezing due to inflammation of bronchi and bronchioles. Emphysema is a chronic disorder in which alveolar walls are damaged, due to which the respiratory surface is decreased.
