Respiration

  1. 1. Pulmonary Respiration <ul><li>Physical act of inhaling oxygen into lungs and exhaling carbon dioxide out. </li></ul><ul><li>Diaphragm and rib muscles contract, causing pressure to decline and air enter (inhale) </li></ul><ul><li>Diaphragm and rib muscles relax causing pressure to increase and air exit (exhale) </li></ul>
  2. 2. The complete seal of the lungs allows this to occur. Injury would cause problems.
  3. 3. Step 1 Step 2
  4. 4. Cellular Respiration Step 3 <ul><li>The process of breaking down glucose (sugar) with oxygen to give cells energy. </li></ul><ul><li>Occurs in each and every cell in the body. </li></ul><ul><li>6O 2 + C 6 H 12 O 6 6CO 2 + 6H 2 O + Energy </li></ul>Oxygen from inhalation Glucose (sugar) from food Carbon Dioxide Exhaled as waste Water used by body or urinated out. Energy cells can now use
  5. 5. Cellular Respiration Step 4 Step 5
  6. 6. Respiratory Diseases <ul><li>SARS – Severe Acute Respiratory Disorder (virus causing fever and trouble breathing) </li></ul><ul><li>Asthma – narrowing of bronchioles </li></ul><ul><li>Emphysema – Damages alveoli </li></ul><ul><li>Allergies – Pollen gets into alveoli </li></ul><ul><li>Bronchitis – Inflamed bronchioles </li></ul>
