I learned about this from an awesome
Hank Green video about how life evolved to move out of the ocean onto land. Developing air breathing lungs was one step in that, and it appears that lungs developed from stomachs. Any soft tissue with a lot of blood flowing through it close to the surface can absorb some oxygen. Some fish began to develops such sacs and use them to gulp and capture airborne oxygen. And he notes that there are some surgeries today where they may “aspirate the patient’s colon” with oxygen to keep their blood oxygen up when conventional breathing must be supplemented. Breathing through your ass is in fact a thing.
This is reminding me of the ‘blood is imitation seawater’ thread on tumblr. Hang on let me grab it.
Ok it’s too long to copy and paste in full without hogging the thread (it’s like 4 or 5 screen shots in length), so here’s the first bit and a link to the rest.
Yeah exactly. Hank Green hints at this in the video title but skin is the biggest problem that had to be solved to move us onto land. How does one keep from drying out? It’s like we made a spacesuit for ourselves and now live in it.
