Lung presentation 2

  1. 1. LUNGS<br />By Demetrius Bates<br />
  2. 2. Respiratory System Brief<br />The lungs are one of six organs in the respiratory system.<br />The other five organs include: nasal cavity, pharynx, larynx, trachea and bronchial tubes.<br />
  3. 3. Functions of the Lung <br />The lungs are essential respiration organ that is located in all breathing mammals.<br />The lungs transport oxygen from the atmosphere into the bloodstream.<br />Then, the lungs release carbon dioxide from the bloodstream back into the atmosphere.<br />
  4. 4. Structure of the Lungs <br />Theoretically, there should be a right an left lung in your chest. <br />The left being smaller than the right lung due to the fact that there is less space in the pleural cavity because of the mass of the heart.<br />The left lung contains only 2 lobes and the right has 3 lobes.<br />
  5. 5. Structure of the Lungs Cont.<br />Each lung consist of bronchi, bronchioles and alveoli.<br />
  6. 6. Structure of the Lungs Cont.<br />Bronchi are pipes leading from the trachea to each lung.<br />Bronchioles are smaller and smaller branches of bronchi.<br />Alveoli are very little small sacs at the ends of the smallest bronchioles where oxygen gets into the blood and carbon dioxide exits.<br />
  7. 7. Structure of the Lungs Cont.<br />The lungs are spongy because they contain air.<br />The lungs are protected by membrane called pleural.<br />
  8. 8. Examples of Ailments of the Lung<br />Asthma: a disease the affects the lungs by the constriction of the bronchial airways. Can cause violent spasms of the bronchi. Maybe caused by various allergens.<br />Emphysema: a pulmonary condition that characterized by destruction of the walls of the alveoli resulting in fewer over expanded air sacs. Can be caused by smoking and sometimes the air you breathe.<br />
  9. 9. Examples of Ailments of the Lung cont’d<br />Pneumonia: an inflammatory condition of the lung that can be caused by bacteria and viral infections, diseases, and chemicals. Resulting in the alveoli spaces filled with fluids.<br />Tuberculosis (TB): an infectious disease caused by bacteria. It affects the respiratory system and causes inflammation and calcification in the lungs.<br />
  10. 10. Visual of Healthy vs. Non Healthy Lungs <br />The lung on the left is a healthy lung and the one the right is an unhealthy lung:<br />
