Emergency device to help air enter the lungs.

the anatomical structures through which air passes on its way to or from the alveoli (lung tissue); the nasopharynx and oropharynx, the larynx, the trachea (wind pipe), bronchi, and bronchioles.

the passage by which air enters and leaves the lungs. Also a tube used to maintain unobstructed breathing.

The tract which involves the movement of air from the nose/mouth to the lungs.

A medical term referring to the passageway from the mouth/nose to the lungs of a patient. Also refers to the plastic devices used by medical personnel to keep this passage open.

the system of the body that is involved in the exchange of oxygen and carbon dioxide. The general term "airway" includes the mouth and nose and goes all the way to the lungs and everything in between.

A metal or plastic framework designed to fit the curvature of the mouth and throat to prevent the air passageways from closing.

The path air follows to get into and out of the lungs. The mouth and nose are the normal entry and exit ports. Entering air then passes through the back of the throat (pharynx), continues through the voice box (larynx), down the trachea, and finally out the branching tubes known as bronchi.

a designated route followed by airplanes in flying from one airport to another

the route for passage of air and/or gases into and out of the lungs.

A path through navigable airspace within which air traffic service is provided.

Designated flight route that an aircraft is required to follow. (This will be replaced with Air Navigation Systems across the globe)

An air route marked by aids to air navigation, such as beacons, radio ranges, and direction-finding equipment, and along which airports are located.

In aviation, an airway is a designated route in the air. Airways are laid-out between navigation aids such as VORs and NDB's (NDB-based airways are rare in the United States, but are more common in much of the rest of the world).

The space between roof insulation and roof boards which allows movement in the air.

The space between a ceiling's insulation and the roof boards that allows air movement through the roofing system's vents, allowing moisture and summer heat buildup to escape.

A space between roof insulation and roof boards provided for movement of air.
