Answer-

  • We often sneeze when we inhale a lot of dust-laden air to expel out these foreign particles.
  • These particles get past the hair in the nasal cavity and irritate the lining of the cavity which triggers a message to the brain.
  • The brain instructs the nasal chamber to initiate sneezing.
  • This is a method to remove unwanted dust particles from the nostrils. Sneezing is a type of defence mechanism used by our body.
