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