Answer 2

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.

Sneezing stops the tickling in our nose for a short while. It blows out the germs and mucus too.

When we cough, it helps clear our throat. We may cough up mucus from our lungs.
