STN member Bill Warren writes,

I was reading about recent discoveries of Dilophosaurus of Jurassic Park fame (the one that spits venom on and kills the computer geek) and it noted that probably most dinosaurs breathed in a uniflow fashion similar to today’s birds. Skeletons are found only in Arizona, so far.

I’d not heard of “uniflow” breathing, and thought to share it if the subject has not been addressed previously.

Among several websites, I found this one that has, in my opinion, the best visual description how uniflow breathing operates. There are textural descriptions that made sense to me until I saw how it works. http://people.eku.edu/ritchisong/birdrespiration.html

It adds a visual how insects breathe, too.

Basically, birds have two sets of air sacs in addition to lungs. The bird inhales which inflates one set of air sacs with oxygenated air. At the same time, the other set of air sacs are filled with carbon dioxide-laden air drawn from the lungs. When the bird exhales, the oxygenated air moves over the lungs and carbon dioxide is expelled. Repeat.

If birds breathed like mammals, they would be unable to fly any distance since mammal breathing is inefficient for high metabolic creatures. Today’s crocodilians still share the trait.
