Table 1 Correlation between compartments of lung deposition, the mechanism of deposition and particle size
From: Interaction of biomedical nanoparticles with the pulmonary immune system
Location | Size (μm) | Mechanism |
|---|---|---|
Primary bronchi | 5–10 | Impaction |
Secondary bronchi | 1–5 | Sedimentation |
Bronchioles | 1–3 | Sedimentation |
Alveoli | 0.5–1 | Brownian motion |
