Breathing Tube

However, by a strange coincidence, an elaborate respiratory function test was in progress, and the breathing-tube inserted in Loren's mouth made conversation impossible. ❋ Clarke, Arthur C. (1986)

The length of the breathing-tube is correlated with the feeding-habits of the larvæ. ❋ Rennie Wilbur Doane (N/A)

Most species have on the eighth abdominal segment a rather long breathing-tube the tip of which is thrust just above the surface of the water when they come up for air. ❋ Rennie Wilbur Doane (N/A)

As the breathing-tube is very short the larvæ must come close to the surface to breathe, and when they are feeding we find them lying just under and parallel to the surface of the water with their curious round heads turned entirely upside down as they feed on the particles that are floating on the surface (Figs. 83, 84). ❋ Rennie Wilbur Doane (N/A)

Those species that feed close to the surface and have the tip of the breathing-tube above the surface most of the time have very small tracheal gills, while those that feed mostly on the bottom have them well developed. ❋ Rennie Wilbur Doane (N/A)

Instead of the breathing-tube on the eighth segment of the abdomen as in the larva, the pupa has two trumpet-shaped tubes on the back of the thorax through which it now gets its air from above the surface. ❋ Rennie Wilbur Doane (N/A)

After the dragonflies and other bugs grew up, the researchers measured their breathing-tube volumes. ❋ Dave Mosher (2010)

Amber fossils are promising if we can more tightly correlate breathing-tube volume to oxygen. ❋ Dave Mosher (2010)

Measurements of insect breathing-tube volume from the experiment could be correlated with that of insects trapped in amber, VandenBrooks said, providing a solid tool to determine oxygen levels in poorly understood eras. ❋ Dave Mosher (2010)

That would involve returning him to surgery, full anesthesia; then the insertion of a silver breathing-tube through the soft pit at the base of his throat, below the Adam’s apple. ❋ REYNOLDS PRICE (1988)
