The immune system

  1. 1. The Immune System Majstorovic Dunja
  2. 2. How does your immune system work?• It is a mechanism designed to defend you against millions of bacteria, microbes, viruses, toxins and parasites that would love to invade your body.• When something dies, its immune system (along with everything else) shuts down.• The immune system is complex, intricate and interesting!
  3. 3. “I feel sick today”• Mechanical damage• Vitamin or mineral deficiency• Organ degradation• Genetic disease• Cancer
  4. 4. Antibodies• Immunoglobulin A (IgA)• Immunoglobulin D (IgD)• Immunoglobulin E (IgE)• Immunoglobulin G (IgG)• Immunoglobulin M (IgM)
  5. 5. Vaccinations• A vaccine is a weakened form of a disease. It is either a killed form of the disease, or it is a similar but less virulent strain. Once inside your body your immune system mounts the same defense, but because the disease is different or weaker you get few or no symptoms of the disease. Now, when the real disease invades your body, your body is able to eliminate it immediately.
  6. 6. Antibiotics• Sometimes your immune system is not able to activate itself quickly enough to outpace the reproductive rate of a certain bacteria, or the bacteria is producing a toxin so quickly that it will cause permanent damage before the immune system can eliminate the bacteria. In these cases it would be nice to help the immune system by killing the offending bacteria directly.
  7. 7. Boost your immune system• Don’t smoke.• Eat a diet high in fruits, vegetables, and whole grains, and low in saturated fat.• Exercise regularly.• Maintain a healthy weight.• Control your blood pressure.• If you drink alcohol, drink only in moderation.• Get adequate sleep.• Take steps to avoid infection, such as washing your hands frequently and cooking meats thoroughly.• Get regular medical screening tests for people in your age group and risk category.
