Following the lizard lung labyrinth.Savannah monitor lizards have a unique airflow pattern that is a hybrid of bird and mammal flow pattern

Take a deep breath in. Slowly let it out.

You have just participated in one of the most profound evolutionary revolutions on Earth—breathing air on land. It’s unclear how the first vertebrates thrived after crawling out of the sea nearly 400 million years ago, but the lungs hold an important clue.

Birds, reptiles, mammals and amphibians have evolved diverse lung structures through which air flows in complicated ways. Birds and mammals are on extreme ends of the airflow spectrum. Mammals inhale oxygen-rich air that funnels into smaller branches, ending in tiny sacs where oxygen enters and carbon dioxide leaves the bloodstream. When mammals exhale, the depleted air follows the same route out of the body, exhibiting a so-called tidal flow pattern.

Thanks for posting this. It's really fascinating. I didn't know about the different types of lungs 🦎

Deep diaphragm breathing! plus the breathing we use in Pilates only in through the nose and out through the mouth. Excellent for us all in more ways than one

I went straight on line and read the report. So very interesting not just because of the possibility of finding answers to problems we have with our lungs. It is so interesting to

learn about the breathing differences in humans, birds and mammals. Really enjoyed it.
