- - - - gas exchange
  - - - simple squamous
      - make up about 95% of alveolar surface area
      - prone to collapse due to high surface tension
    - - almost cuboidal-shaped
      - secrete pulmonary surfacant
        
        opposes surface tension and prevents the collapse of alveoli
    - - leukocyte
        
        fixed or free
        
        engulfs any microorganisms or particulate material that reaches the alveoli
- - - - P ∝ C (or) P = kH.C
  - - - P{1}V{1}=P{2}V{2}
  - - - PTotal = Pgas1 + Pgas2 + Pgas3
- - - - death
  - - - pneumonia caused by bacteria, viruses or fungi
        
        weekend immune system
    - - bacterium
        
        reach major organs and result in organ damage or death
    - - bacteria can invade the heart and cause damage
        
        CHF
    - - inflammation causes alveoli to fill up with fluid or pus
        
        lead to trouble breathing, coughing, coughing up yellow or brown mucous
