Each day we breathe about 20,000 times. All of this breathing couldn't happen without help from the respiratory system, which includes the nose, trachea, diaphram and lungs. With each breath, you take in air through your nostrils and mouth, and your lungs fill up and empty out. As air is inhaled, the mucous membranes of the nose and mouth warm and humidify the air.

   It is important for everyone to know at least the basics of the Respiratory System. It will help individuals understand their body more and how to take care of it too its fullest.
