RESPIRATORY SYSTEM 

We use the respiratory system to breath and if we dont have the lungs we are not a live.
There are 2 processes involed in the respiration ; inspiration and expiration 
Inspiration is whe the air enter in the lungs
expiration is whe you eject the air
In the inspiration part of the air pases to be nutriens that trow pass the ecirculatory system 
The respiratory have  conection whit the circulatory, digestive and excretory system. 


The parts of the respiratory system are: nostrils, pharynx, mouth, windpipe, larynx, bronchus, bronchioles, diaphagram and lungs 

One  dieases of the respiratory system is Pneumoconiosis and smoke is not a diease but is very bad for the human body because the bad air  state in the lung and the lungs they began to die. I think tat is imposible to stay 20minutes in the water without breading, but is the most a person stay in the water. And for finaly I am going to tell that we breath 13 litres in a minute that is the same that breath 9 to 20 times in a minute
