BIOXI17: BREATHING AND EXCHANGE OF GASES

338672 Due to increasing air-borne allergens and pollutants, many people in urban areas are suffering from respiratory disorder causing wheezing due to

1 Benign growth on mucous lining of nasal cavity

2 Inflammation of bronchi and bronchioles

3 Proliferation of fibrous tissues and damage of the alveolar walls

4 Reduction in the secretion of surfactants by pneumocytes.

NEET - 2019

338673 Which of the following options correctly represents the lung conditions in asthma and emphysema, respectively?

1 Increased respiratory surface; Inflammation of bronchioles

2 Increased number of bronchioles; Increased respiratory surface

3 Inflammation of bronchioles; decreased respiratory surface

4 Decreased respiratory surface; Inflammation of bronchioles

Explanation:

Emphysema is a chronic disorder in which alveoli become fewer and larger as the alveolar walls are damaged. Respiratory surface is decreased. Hence gas exchange is affected leading to low arterial ${pO}_{2}$ .
