Why you need to Cough (VIDEO)


Why does a person need a cough?

After all, it is always disturbing and does not seem to help anything.
But in fact, it's not that simple. 

Coughing is a physiological defense mechanism, whose task is to restore the patency of the airways. 
Roughly speaking, "to clear the clogged pipes." 

"Debris" can be a foreign body (children often inhale small toys), pieces of food (these are situations when a person chokes) or mucus secreted during an inflammatory process.

This is a micro-landscape of respiratory cells, with an accumulating layer of mucus from bacteria and toxins. As you can see, through coughing, the body manages to get rid of them.
