About RESPIRATORY SYSTEM

I am weak in respiretery system, so I did research.
The most common respiratory disease is smoking and
breathing in air pollution.i myself do not like breathing
in air pollution and smoke.When we hiccup, cough and sneeze,
we will remember the respiratory system.We tend to forget
the respiratary system.cough is the way your system clears the airway.
A sneeze is caused by an irritation in the upper airway.
Hiccups tend to be VeRy annoying to people.
