Upper lung field distribution

  • The upper lung zones have a higher concentration of alveoli,
  • Beryllium particles can become trapped in the alveoli
  • stimulate an immune response,
  • leading to
      • inflammation and
      • scarring.
  • The upper lung zones have a
      • higher oxygen concentration than the lower lung zones,
      • may promote the
        • oxidative stress and
        • immune response that underlie berylliosis.
