Inflating a set of cat lungs
Lungs are by most accounts mundane. Everybody has them, few give it much thought. But sequestered within darkness of the chest cavity, enveloping the fluttering heart, there’s a incredible wonder to this oddly inflatable organ.
Dissection is a destructive process. Rudely excised from membranous mooring and nourishing vessels, the deflated lungs appear little more than bloodied meat; amorphous and exposed…….until a breath of air unfurls its secret glory.
Here, a set of cat lungs is inflated with a straw. Comprised of hundreds of millions of microscopic air sacks called aveoli, Mammalian lungs harbor air capacity that is difficult to believe unless seen. The color of the entire organ lightens into a soft pink, as each microscopic sac fills with air.
A debt of gratitude is owed to cyborgraptor for her assistance in creating these gifs, as well as the students that help me film this demo.
Public service announcement: You essentially have balloons inside your chest. There’s some really great anatomy GIFs and images on that blog, too.
The more I learn of how we we function, the more amazed that we do at all.
Everyone just got home from wasted sledding. Ben dropped the whiskey and it went further than everyone combined and Justin got a concussion. We turned cards against humanity in to a drinking game and then I made a friend named beth ( who Ben promptly offended). Tonight had everything but you.
And that’s the most frustrating thing about depression. It isn’t always something you can fight back against with hope. It isn’t even something — it’s nothing. And you can’t combat nothing. You can’t fill it up. You can’t cover it. It’s just there, pulling the meaning out of everything. That being the case, all the hopeful, proactive solutions start to sound completely insane in contrast to the scope of the problem.
It would be like having a bunch of dead fish, but no one around you will acknowledge that the fish are dead. Instead, they offer to help you look for the fish or try to help you figure out why they disappeared.
This is actually a really good way to explain it, I think.
I WILL NEVER NOT REBLOG THIS
