Resource summary

Emphysema
  1. Causes
    1. Smoking
      1. Causes tar build up on the lungs
      2. Excessive Dust Inhalation
      3. Effects on Lung Capacity
        1. Damages Elastic Tissue
          1. Cannot recoil as normal
            1. Remains permanently stretched
          2. Less air leaves the lungs
            1. Diffusion gradient is reduced
              1. Less oxygen reaches tissues for respiration
          3. Effects on alveoli
            1. Alveolar cross wall begins to break down
              1. Reducing surface area for diffusion
              2. Alveoli begin to fill with fluid
                1. Reduces surface area for diffusion
