Lesson 17: Respiratory System Disorders

The respiratory system is the part of your body that allows you to take in fresh, oxygen rich air that all your cells need to function well. In addition, this system allows you to breathe out the waste product carbon dioxide that your cells produce as a by product of energy production. Many conditions can interfere with this essential process. You will learn about asthma, bronchitis, and the effects of smoking and air pollution.
