Answer:Sneezing expels the foreign particles from the inhaled air, so that only clean air enters our
body. It usually occurs because of the irritation in the upper breathing passage. This irritation
happens when we inhale some unwanted particles and they get trapped in our nasal cavity. Smoke,
dust, pollen, etc. are some of the unwanted particles that may cause sneezing.
