  • 1. EMPHYSEMABy: Rolla Tyas AmaliaGrade: 11
  • 2. What is Emphysema? A condition in our body in which the air sacs of the lungs, called alveolus are damaged and enlarge, causing breathlessness.
  • 3. How Does It Happen?1. Constant inflammation that occurs to our lungs will cause infection and existence of bacteria.2. Phagocyte that work in white blood cells to remove bacteria from our body will go to our lungs when they’re infected.
  • 4. 3. Phagocytes release protein digesting enzyme elastase on their way to reach lungs from capillaries.4. That enzyme destroys elastin in the walls of the alveoli.
  • 5. 5. Our body needs elastin to take responsibility for the recoil of the alveoli when we breath out.6. When the elastin is decreased because of that enzymes, a large space appears and reduces the surface area for gaseous change.
  • 6. What are the Effects to OurBody?  People with emphysema will not oxygenated their blood well.  They can’t remove carbon dioxide from their blood and lungs.  They have a rapid breathing rate.
  • 7. Symptoms Rapid breathing rate Wheezing Coughing Chest Pain
  • 8. Causes of Emphysema: Cigarette smoking Air pollution Gender; men are more likely to develop emphysema than women People’s age; older age is a risk factor for emphysema
  • 9. Treatments:It depends on the disease’s level: Mild level: Medications and daily exercise Moderate level: Medications, use of inhalers, and daily exercise. Severe level: Medications and surgery.
  • 10. The most efficient solutions for us to keep away from the disease are to stop smoking or say no to smoking habit, and avoid all exposure to cigarette smoke and lung irritants.
