- Pharynx: Common passageway for air and food.
- Larynx: Guards the entrance to the trachea
- Trachea: known as windpipe the trachea contains Cartilaginous rings that prevents the trachea from collapsing.
- Bronchus: include being a conduit for air during inhalation and exhalation.
- Alveoli: Exchange of gases from blood to air (carbon dioxide) and air to blood (oxygen)
Because of alveoli
- Epiglottis: is to block off food and liquids from entering the trachea
- Inhalation: Inhalation is a process where you intake oxygen through the nostrils.
- Exhalation: exhalation is breathing out carbon dioxide through the same airways.
- Oxygen goes into the air sacs(alveoli).
- Oxygen goes to the cell through the blood capillaries
- The cells burn the oxygen and food to release energy
- Energy and carbon dioxide goes out through the blood capillaries
- Smoking affects every organ in the body, But one of the organs that is most directly affected is the lungs.
- When somebody starts smoking this causes irritation of the cells lining the air tubes within the lungs (the bronchi and bronchioles).
- One of the body's basic responses to this is to produce mucus.
- This mucus can reduce the diameter of the air tubes making it more difficult to breathe.

Protection for the Respiratory System
- Do not smoke!
- Do not contribute to air pollution
- Maintain clean, dust-free surroundings
- Get regular exercise
- Do respiratory therapy
- Get extra medication and a healthy diet
Effect of smoking on lungs.
Smoking and Lung Cancer
- Women who smoke either current or former and take hormone therapy are at much higher risk of developing lung cancer.
- the time when your smoking increases the person has a higher chance of getting lung cancer.
- passive smoking is also a cause of lung cancer.
