Talk:Respiratory system

Birds

"The trachea, which in some cranes can be 1.5 m long, is coiled back and forth within the body, drastically increasing the dead space ventilation"

" The purpose of this extraordinary feature is unknown"

I thought this was well understood. Apparently swans (and similar) birds have long necks to provide a constant amount of re-breathed air (eg a built-in inefficiency threshold).

Because their lungs are tied to their flight muscles, they would overbreath at cruising speed. So the long necks provide just the right amount of re-breathed CO2 to offset this, while still allowing a drastic increase in efficiency when extra effort is expended. — Preceding unsigned comment added by 180.150.22.107 (talk) 02:47, 13 October 2021 (UTC)

respiratory tract

I have added "respiratory tract" to the list under "See also". I think the respiratory tract is part of the respiratory system: The respiratory system is not a part of the respiratory tract, but comparing the two articles it seens they would have you believe that the respiratory system is part of the respiratory tract and that the respiratory tract is not completely encluded by the term "respiratory system".

Entrance of Air

Air can enter the respiratory system through the mouth or oral cavity as well as the nostrils and nasal cavity, it doesn't seem to acknowledge this... — Preceding unsigned comment added by Chem Lady (talk • contribs) 00:52, 15 December 2006 (UTC)

Medical treatment, surgical procedures and equipment?

How should medical articles related to the Respiratory system be linked to the category? I just did a change on Flutter valve to this category from where it was inexplicably pointed to Digestive system. Hmm, there doesn't seem to actually be a Respiratory system *category*, just this article. — Preceding unsigned comment added by Bizzybody (talk • contribs) 07:16, 28 June 2007 (UTC)
