A 70 year old woman with a viral infection in the lungs paired with…

- - - - spongy, air-filled organ that receives air into the bronchi via the trachea
      - Bronchi
        
        airways that lead from the trachea into the lungs and branch into smaller bronchioles
        
        made up of hyalin cartilage for stability and prevent collapsing
    - - lung tissue inflammation
        
        the alveoli of the lungs fill with fluid causing inflammation and difficulty breathing
        
        symptom of pneumonia
        
        caused by viral infection
    - - tiny sacs located within the lungs that allow for oxygen and carbon dioxide to move between the lungs and blood
      - located in the alveolar sacs of the lungs in the pulmonary lobules of the respiratory zone
      - smallest functional unit of respiratory tract
  - - - Alveoli
        
        transport oxygen into the bloodstream for transport to the tissues
        
        remove carbon dioxide from the bloodstream
    - - Henry's Law
        
        a law stating that at a constant temperature, the amount of gas that dissolves in a liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid
      - Boyle's Law
        
        a law stating that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature
      - Dalton's law
        
        a law that states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases
    - - pressure exerted by each gas within a mixture of gasses
      - measured in mmHg
      - total pressure x % of gas = partial pressure of that gas
      - partial pressure gradient
        
        exists when partial pressure for a specific gas is higher in one region than another
        
        PO2 and PCO2 in the alveoli
        
        air from the environment mixes with air remaining in the anatomic dead space in the respiratory tract
        
        oxygen diffuses out of the alveoli into the blood and carbon dioxide diffuses from the blood into the alveoli
        
        more water vapor is present within the alveoli because of the higher humidity
        
        within the alveoli the percentage of oxygen is lower and the percentage of carbon dioxide is higher than in the atmosphere
- - - - pneumonia
        
        fluid in the lungs
        
        less lung capacity for oxygen
        
        coughing in an attempt to get more oxygen
  - - - outside pressure is lower than inside the lungs
      - makes it more difficult to pull in oxygen
      - circulatory system has to work harder to deliver oxygen
    - - old age requires longer recovery time with viral infection
      - immune system is typically weaker
      - less likely to catch on to the problem
- - - - immune system
        
        weakened immune system due to age
        
        death of T-cells if viral infection spreads
      - cardiovascular system
        
        fast heart beat
        
        infection travels in the blood and can lead to septic shock and death
        
        low BP due to overworked heart
        
        organ failure
        
        infarction
      - muscular system
        
        weakness
        
        fever
        
        chills
        
        lack of oxygen causes muscle dysfunction
