70 year old female patient, difficulty breathing, has viral infection, wet…

- - - - Bronchioles
        
        respiratory bronchioles
        
        alveolar ducts - gas exchange
        
        alveoli - gas exchange
        
        alveoli type I cells - make up 95% of alveolar surface and simple squamous epithelium
        
        alveoli type II cells - secrete pulmonary surfactant, prevents collapse of alveoli
  - - - redness
        
        heat
        
        swelling
        
        pain
  - - - oxygen ultimately diffuses from the blood into the alveoli
        
        more water vapor is inside the alveoli because of humidity being higher
    - - it is low in the blood of the pulmonary capillaries
    - - exchanged between the alveoli and pulmonary capillaries
- - - - colder weather
- - - - heart failure - due to the bacteria, it can invade the hearts muscle and cause damage
        
        organ failure - lungs can be so impacted that not enough oxygen enters the bloodstream and organs start shutting down
        
        death
- - - - decreases pp of the atmosphere and the oxygen
  - - - amount of air inhaled that can be inhaled beyond tidal volume
      - 3100 mL
    - - amount of air inhaled or exhaled per breath during quiet breathing
      - 500 mL
    - - amount of volume can be exhaled beyond tidal volume
      - 1100 mL
- - - - develop another infection
        
        be on ventilation
        
        life support
- - - - plasma cells makes antibodies
        
        antibodies fight off infection
- - - - low oxygen levels
        
        can lead to organ failure
