    1. 1. Respiratory System: Asthma Alaa Mahmood
    2. 2. why?My sisterCousinMeAs of 2010, 300 million people wereaffected worldwide.In 2009, asthma caused 250,000 deathsglobally.
    3. 3. Respiratory SystemThe respiratory system is theoperator of the whole body.The lungs take in: the noseinhales O2 and exhales CO2.This makes our body pumpblood and nutrients all overthe body and brain andfunction properly.
    4. 4. what is asthma?Is an inflammatory disorder of the airways, which causesattacks of wheezing, shortness of breath, chest tightness,and coughing.This affects the Respiratory system.
    5. 5. types of asthmaExercise induced Asthma Airway narrowing peaks five to 20 minutes after exercise begins, making it difficult to catch your breath.Allergies and Asthma With allergic rhinitis, you may feel a constant runny nose, ongoing sneezing, swollen nasal passages, excess mucus, weepy eyes, and a scratchy throat.Cough-Variant Asthma Cough-variant asthma is somewhat difficult to diagnose because the cough may be the only symptom, and cough itself may appear to be bronchitis or cough associated with postnasal drip.
    6. 6. Symptoms and Diagnosis Symptoms: Wheezing Coughing Chest tightness Shortness of breath Diagnosis:• Wheezing—high-pitched whistling sounds when breathing out—especially in children. (Lack of wheezing and a normal chest examination do not exclude asthma.)• history of any of the following: • Cough, worse particularly at night • Recurrent wheeze • Recurrent difficulty in breathing • Recurrent chest tightness • Prevent allergens and irritants.
    7. 7. originCaused by both genetic and environmentalfactorsThese factors influence how severe asthma isand how well it responds to medication. Theinteraction is complex and not fullyunderstood.Asthma people have more allergic reactions.
    8. 8. Allergy Allergy testing may be helpful to identify allergens in people with persistent asthma. Common allergens include: • Cockroach allergens • Dust mites • Molds • Pet dander • Pollens • ColdCommon respiratory irritants include: • Fumes from burning wood or gas • Pollution • Tobacco smoke
    9. 9. Causes Symptoms occur or worsen in the presence of:• Exercise• Viral infection• Animals with fur or hair• House-dust mites (in mattresses, pillows, upholstered furniture, carpets)• Mold• Smoke (tobacco, wood)• Pollen• Changes in weather• Strong emotional expression (laughing, stress or crying hard)• Airborne chemicals or dusts• Menstrual cycles• Symptoms occur and worsen at night, awakening the patient
    10. 10. affecting the bodyThe body is affected with Asthma by: the circulatory system not functioning properly and the natural pumping of the heart would decrease because there is not much O2 passing in and the circulation is affected. not enough O2 is delivered (sometimes) to the brain and body which causes serious damage to the body and brain and sometimes may cause death (Asthma attack).Asthma Attack - when your not able to breathe, and you have a airwayinflammation.
    11. 11. Treatments and cures Asthma can be treated by medicines and treatments, and we can control the airway inflammation, but over all asthma can’t be cured. Medicines and Inhalers are given to reduce the symptoms and ease the irritation. No cure.
    12. 12. Current Researchasthma on the rise theories: more cleaners and disinfecting sprays and etc. are maybe causing the kids at a young age to have asthma. more smokers in the present and future (maybe) than the past. drugs related also. no cures found yet.
