Welcome to the Respiratory system page 
The respiratory system is involved in breathing or respiration, which means inhaling Oxygen and exhaling Carbon Dioxide and other waste products.
The average respiration is 70/minute.
The faster we breathe the more Oxygen we take in, as in exersizing.
Smoking and other pollutants can destroy the lungs and make breathing very difficult......!!!!!!
