turbinal การใช้

• Researchers first recognized the value of turbinals three decades ago in kangaroo rats.
• It showed no signs of turbinals.
• When Freud looked in Irma s throat he saw a white scab on the turbinal bone.
• As a result, Glanosuchus'turbinals had little time to humidify the incoming air and return water to the lungs.
• As the animal exhales warm, moist air from its lungs, the moisture condenses onto the cool surfaces of the turbinals.
• What that suggests, Hillenius argues, is that turbinals aren't adaptations to deserts _ they're adaptations to being warmblooded.
• The next breath of cool, dry air from the outside world cools the turbinals again and also dries them, carrying water vapor back to the lungs.
• The paper-thin turbinals themselves rarely survive fossilization, but the distinctive ridges along which the turbinals attach to the internal walls of the nose often do.

• Inspired by the success of his experiments with modern mammals, Hillenius decided to do a systematic search for turbinal ridges in the fossil skulls of mammallike reptiles.
• Then he deprived them of the use of their turbinals _ by plugging their nostrils and thereby forcing them to breathe through their mouth _ and repeated the measurements.
• Most of the time, though, paleontologists had ignored maxilloturbinals or confused them with other turbinals that both reptiles and mammals use for smelling rather than for recycling water.
• From the way the animals'breath became more humid, Hillenius calculated that their turbinals ordinarily reclaim as much as 45 percent of the water from the air they exhale.
• But in the 260-million-year-old skull of an animal named Glanosuchus _ and in all the mammallike reptiles that followed Glanosuchus _ Hillenius saw distinct turbinal ridges.
• But in Hillenius'view, their turbinals are simply an improved version of an apparatus that first evolved when warmbloodedness itself did, as a way of preventing dehydration from rapid breathing.
