The alveoli contain specialised cells that secrete a phospholipoprotein complex known as pulmonary surfactant. The function of pulmonary surfactant is:
  • a)
    to provide some rigidity to the alveoli to prevent lung collapse
  • b)
    to decrease the surface tension of the alveoli, making it easier to expand them
  • c)
    to facilitate the diffusion of O2 and CO2 by providing protein channels through which these gases flow  
  • d)
    to provide a sticky surface upon which dust and microbes are trapped and disposed of
Correct answer is option 'B'. Can you explain this answer?
