How do coughing and sneezing protect your respiratory system?

Answer 1

Sneezing is actually caused by irritations in the nose, when you sneeze air goes very fast, normally getting rid of the irritation. These irritations can be caused by dust or other such things. Most dust or irritations don't get into your nose though, because of the tiny hairs that protect your inner nostrils.

Coughing is a involuntary thing, it is caused by the brain trying to clear the body's airways, people cough more these days, normally from the more pollution in the air, like cigarette smoke, car exhaust and other such things.

Answer 2

i am not sure right now, but maybe sneezing is just a way of the nose telling your body to get dust particles and such out of your nose because the little airs in your nose are supposed to protect it. and coughing no idea hope i helped! :)

Answer 3

Coughing helps to expel irritants or mucus from the airways, preventing them from reaching the lungs and causing infection. Sneezing forcefully expels irritants from the nasal passages before they can enter the respiratory system, helping to protect against infections in the upper respiratory tract. Both mechanisms are natural defense mechanisms that help to keep the respiratory system clear and healthy.

Answer 4

Every time you sneeze, thousands of tiny droplets are blasted out of your mouth. If you have a cold, those droplets might spread the cold to other people.
