Alligator Breathing Sheds Light on Rise of Dinosaurs

Alligators breathe like birds, scientists have discovered.

"They cannot argue with this data," she said. "I have three lines of evidence. If they don't believe it, they need to get an alligator and make their own measurements."

Bird breath ping.

They breath like birds......what in and out?

No. Not in and out. That is the point of the article and the research.

Get an alligator and make your own measurements.

It is in and out. It’s just that she says that there is no dead-end to the bronchi in allagators, same as birds. It’s a one-way loop.

Air goes in air goes out. I mean it doesn’t go in and stay there. (Otherwise the birds would blow up.)

No, in and out is not how birds breath, and process oxygen. You might want to take a look at this article, it it isn’t too much trouble.

Enlighten us. After the air goes into the bird, where does it go?

“All of these experiments showed the same result: The air flowed through the lungs in just one direction.

The unidirectional flow is caused by aerodynamic valves in the lungs: Air is inhaled through the trachea, or windpipe, then flows into two primary bronchi, or airways, each of which enters one of the alligator’s lungs. The bronchi branch into narrower airways, the first of which is bypassed by the incoming air because that branch makes a hairpin turn that acts as an aerodynamic valve; instead, the air flows into other bronchi, and down into even smaller airways where gases are exchanged with the blood.

The air, still moving in one direction, then flows from the smaller bronchi into the bypassed airway and then out of the lungs, completing a one-way loop.”

That’s interesting.

Blow them up with helium and they really sound funny. Blow an alligator up with helium and you have a really nasty bird.

Why don’t you read the damn article? It has a good description of the breathing processes of birds and amphibians.

Let me help you. From the article: The air, still moving in one direction, then flows from the smaller bronchi into the bypassed airway and then OUT of the lungs, completing a one-way loop.”

And you think that is how your lungs work?

You sound like Ms Farmer - "Get your own damned alligator!"

To: La Lydia

No. The article clearly states that the difference between mammal and avian is that mammal bronchi end in alvioli which are dead ends. Avian lungs operate ina open-ended air passage allowing the air to flow in a loop.

Ok, I get the unidirectional lung. What I am saying is that air goes in air goes out, otherwise the bird would puff up and explode. The air does not stay in the bird, it goes out after it goes in.

Okay now, count to ten and breath in - breath out, breath in - breath out...

Yuor reply is so right-on true that I laugh out-loud thinking there is someone on here who doesn’t get it. Are you reading this LL?
