Due to increasing air-borne allergens and pollutants,
many people in urban areas are suffering from
respiratory disorder that cause wheezing due to
(a) reduction in the secretion of surfactant by
pneumocytes
(b) benign growth on mucous lining of nasal cavity
(c) inflammation of bronchi and bronchioles
(d) proliferation of fibrous tissues and damage of
the alveolar walls.
