1. The Respiratory System By Matt Cruz and John Miles

2. Main Organs  Mouth and Nose  Trachea  Lungs  Diaphragm

3. Mouth and Nose  Where oxygen enters the respiratory system  cleans the air of dust  warms the air if it is too cool  moistens the air if it is dry

4. Trachea  Connects the pharynx and larynx to the lungs.  Produces mucus which traps particles

5. Lungs  Deoxygenated blood is pumped into the pulmonary artery.  oxygen diffuses into blood and is exchanged with carbon dioxide.

6. Diaphragm  separates thoracic cavity from abdominal cavity  Expansion and contraction causes respiration

7. Dysfunctions  Bronchitis  Pneumonia  COPD

8. Bronchitis  Acute  Cough  Possible mucus  Chronic  Productive cough  Wheezing  Sever mucus (yellow or green with streaks of blood)  Two categories  Acute  Chronic

9. COPD  chronic obstructive pulmonary disease  Limits air flow causing shortness of breath  Caused by toxic particles or gas most commonly from smoking

10. Pneumonia  Typically caused by infection  Symptoms:  Cough  Chest pain  Fever  Difficulty breathing
