Question

why do we sneeze and cough??????​

Answer 1

Answer:

"When we catch a cold, germs spread to our nose, throat and other air passages. Our body fights off the germs and produces a slimy mucus to get rid of them. Sneezing and coughing blows out the germs with the mucus. ... When we cough, it helps clear our throat."

Answer 2

Explanation:

Sneezing is a mechanism your body uses to clear the nose. When foreign matter such as dirt, pollen, smoke, or dust enters the nostrils, the nose may become irritated or tickled. When this happens, your body does what it needs to do to clear the nose — it causes a sneeze. A sneeze is one of your body’s first defenses against invading bacteria and bugs.
