In Response To: Alligator and Elite lungs (for Jilly) (scarab) : I just saw this: http://www.sciencemag.org/cgi/content/short/327/5963/338 : The Halo significance is that I posted some ideas about Elite lungs here some
: Jilly asked me to explain and I tried to write a post but it got so long and
: But I know that Jilly can access this
: In short: the mesobronchus is the key, as long as there are some connections
: The significance for my ideas on Elite lungs is that: there is no
: I thought that the potential for one way air flow has always been inherent in
: This has evolutionary and phylogenetic significance because it suggests that
: But getting back to Elite lungs... : I imagined that the Elites had a single lung, wrapped around the heart (that

: Ventilation would be achieved via a diaphragm piston and two air sacs. : Imagine the lung suspended in the center of the chest cavity. : Imagine an epithelium, a thin elastic layer of tissue that lines the chest
: Imagine that the pleura lines the chest cavity but also meets at the center
: Imagine that there are openings between the left respiratory diverticulum
: The air sacs expand and contract as the diaphragm moves down and up. : Put valves where the trachii meet the mouth/throat/whatever-its-called. : When the Elite inhales the left/foregut-derived trachea valve opens and air
: Air passes down the left trachea and enters the left air sac/cavity directly. : The only way that it can reach the right air cavity is via the lung. : When the Elite exhales the left valve shuts and the right valve opens. : Air travels directly from the right pleural cavity through the right trachea
: Air in the left pleural cavity passes through the lung and out via the right
: So air passes through the system in one direction whilst the animal inhales
: If you look at the rear of a h2 Elite's mouth and examine the orifice you
: Anyway, if anyone is interested then I can explain my ideas on the Elite
That sounds like a really nice analysis. I followed most of it I think. :) The Elites have a 'double heart', make of that what you will. It's been mentioned in both Ghosts of Onyx ("listened to three beats of his hearts", p. 226), suggesting two distinct organs, as well as The Cole Protocol ("Sangheili double hearts could take far more acceleration than Jiralhanae or Kig-Yar...", p. 161. As well, I wonder if you might get some visual reference from the Elite from Halo 1 with its chest splayed open. It was in the Jenkins camera cutscene, but something tells me I've seen one before either elsewhere in the game or in a Custom Edition map where a good look could be had. I'll fish around for a screenshot. As far as breathing goes, we know their inhalation/exhalation routine is similar to a human as their idle form (Halo 3 co-op menu screen, for example) shows regular breathing. Also, the Heretic Elites in Halo 2 had special breathing devices in their mouths and you could probably time their breath cycles if it would help you any. Keep up the analysis!
