Question

Why does the body, as a self defensive response to some sicknesses, swell the nose so you can’t breathe?

In: Biology

Answer 1

Your body is like downtown traffic and getting the flu is like a virus trying to rob a bank in your nose. The viruses run into all the bank vault cells creating mucous and chaos and runny noses. Swat teams of white blood come to get rid of the virus causing swelling and inflammation traffic jams of the nasal passages. They are trying to get rid of the virus quickly before it can spread too much and cause a bigger problem than they can handle. The white blood cells know they are congesting nasal traffic, but doing nothing would mean the virus wins.
