Air Sacs
Linked via "body volume"
| Intrapulmonary Sac (IPS) | Within Lung Parenchyma | Oxygen sequestration; prone to minor vacuum collapse |
The total capacity of the air sac system can constitute up to $25\%$ of the bird's total body volume, though this ratio is often inversely proportional to the bird’s structural density, as noted in heavier, ground-dwelling species like the Struthio camelus (Ostrich) [2].
