airspaces
Regulated overhead regions
Airspaces is the plural of airspace—the atmosphere above a particular territory, typically under a nation's jurisdiction.
Countries control who may fly through their airspace: The plane was shot down after entering hostile airspaces.
In anatomy, airspaces are the air-filled cavities in lungs or sinuses.
In architecture, they're gaps left for insulation or ventilation.
