When the animal exhales, nearly all of the air flows towards the front of the lung and out of the trachea in a net unidirectional flow. At the beginning of inhalation, air enters through the ...

There had been some suggestion that alligators might breathe via unidirectional air flow, too, but no one had conclusively illustrated that this was the case.

Unidirectional air flow in birds long has been attributed to air sacs in the lungs. But Farmer disagrees, since gators don't have air sacs, and says it's due to aerodynamic "valves" within the lungs.

The ability to position the agar surface related to the position of unidirectional air flow, avoiding laminar flow turbulence, make the TRIO.SETTLE an ideal cleanroom accessory.

When the animal exhales, nearly all of the air flows towards the front of the lung and out of the trachea in a net unidirectional flow. At the beginning of inhalation, air enters through the ...

Lungs with one-way air flow may have helped dinosaurs’ ancestors become dominant when oxygen levels dropped after the Permian-Triassic extinction. It was a period around 250 million years ago ...

The simplified apparatus was, as Audus's, actuated by unidirectional air flow and was used for months in experiments that demanded a control of composition of the inflowing gas.

When the animal exhales, nearly all of the air flows towards the front of the lung and out of the trachea in a net unidirectional flow. At the beginning of inhalation, air enters through the ...
