Katherine Colon's Biology Slide Show 1

  1. 1. Lungs Katherine Colon
  2. 2. <ul><li>Lungs are major organs of respiration. The lungs consist of air passageways, the bronchi and the air sacs, alveoli. Gas exchange takes place with in the alveoli. </li></ul><ul><li>Alveoli are tiny air sacs at the end of each bronchiole The alveoli are surrounded by a capillary network. Gas exchange takes place as oxygen and carbon dioxide diffuse across the alveolar and capillary walls. </li></ul><ul><li>With out the lungs it is very difficult for one to breath comfortably. The lungs also work hand in hand with the rest of the human body. Not only do humans have lungs but many animals do as well. </li></ul><ul><li>The lungs are apart of the respiratory system, the respiratory system brings oxygen into the lungs and expels carbon dioxide. </li></ul>
  3. 3. <ul><li>The body does not need carbon dioxide so, as you begin to exhale that carbon dioxide, your body breathes in what it needs which is oxygen. </li></ul><ul><li>AS stated in nationalgeographic.com “Since the lungs process air, they are the only internal organs that are constantly exposed to the external environment. Central to the human respiratory system, they breathe in between 2,100 and 2,400 gallons (8,000 and 9,000 liters) of air each day—the amount needed to oxygenate the 2,400 gallons (9,000 liters) or so of blood that is pumped through the heart daily.” </li></ul>
  4. 5. Lung Conditions <ul><li>Chronic bronchitis: Repeated, frequent episodes of productive cough, usually caused by smoking. Breathing also becomes difficult. </li></ul><ul><li>Pneumonia : Infection in one or both lungs. Bacteria, especially Streptococcus pneumoniae, are the most common cause. </li></ul><ul><li>Acute bronchitis: An infection of the lungs' large airways (bronchi), usually caused by a virus. Cough is the main symptom of acute bronchitis. </li></ul><ul><li>Asthma:The lungs' airways (bronchi) become inflamed and can spasm, causing shortness of breath and wheezing. Allergies, viral infections, or air pollution often trigger asthma symptoms. </li></ul><ul><li>Pleurisy: Inflammation of the lining of the lung (pleura), which often causes pain when breathing in. Autoimmune conditions, infections, or a pulmonary embolism may cause pleurisy. </li></ul><ul><li>Cystic fibrosis:A genetic condition in which mucus does not clear easily from the airways. The excess mucus causes repeated episodes of bronchitis and pneumonia throughout life. </li></ul>
  5. 7. Lung Diseases <ul><li>Lung cancer : Cancer may affect almost any part of the lung. Most lung cancer is caused by smoking </li></ul><ul><li>Tuberculosis : A slowly progressive pneumonia caused by the bacteria Mycobacterium tuberculosis. Chronic cough, fever, weight loss, and night sweats are common symptoms of tuberculosis. </li></ul><ul><li>Severe acute respiratory syndrome ( SARS): A severe pneumonia caused by a specific virus first discovered in Asia in 2002. Worldwide prevention measures seem to have controlled SARS, which has caused no deaths in the U.S. </li></ul><ul><li>Emphysema : A form of COPD(Chronic obstructive pulmonary disease) usually caused by smoking. The fragile walls between the lungs' air sacs (alveoli) are damaged, trapping air in the lungs and making breathing difficult. </li></ul>
  6. 8. What are the symptoms of lung disease? <ul><li>For symptoms of lung cancer there are no symptoms it most often is discovered by a routine chest x-ray or CT scan. </li></ul><ul><li>Symptoms related to lung cancer however are: </li></ul><ul><li>coughing up blood (hemoptysis), chest pain, shortness of breath </li></ul><ul><li>For some conditions like asthma some symptoms may be: </li></ul><ul><li>Wheezing, shortness of breath, gasping for air, cough </li></ul>
  7. 9. <ul><li>The lungs as you can see are overall very important. </li></ul><ul><li>To help prevent diseases and some cancers eating healthy and not smoking can go a long way for your lungs. </li></ul><ul><li>Also remember second hand smoke can be just as harmful as smoking. </li></ul>
