Question

why do we often sneeze when we inhale a lot of dust laden air.











​

Answer 1

Answer:

When we inhale air containing dust particles, the particles get trapped in the hair present in nostrils. they irritate the mucus lining of the nasal cavity, and as a result we sneeze.

Answer 2

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 the unwanted dust particles from the nostrils. Sneezing is a type of defense mechanism used by our body.

• A sneeze is a powerful, involuntary expulsion of air. Sneezing often happens suddenly and without warning. Another name for sneezing is sternutation.

• Sometimes, however, dirt and debris can enter your nose and irritate the sensitive mucous membranes inside your nose and throat. When these membranes become irritated, it causes you to sneeze.
