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.

10 Things You Probably Didn’t Know About Coffee

Are you addicted to your morning cup of coffee? Though caffeine takes about 15 to 20 minutes to kick in, its effects can last up to 14 hours, depending on the person. No wonder coffee is so addictive!

Of course, different coffees contain different amounts of caffeine, but contrary to what many may believe, light roasts tend to contain more caffeine than dark roasts. It should also be noted that decaf does not mean the coffee contains zero caffeine.

Surprisingly, beyond coffee and tea there are 60 plants that contain caffeine. 90% of the world uses caffeine in some form or another. Be careful not to take in too much caffeine, as 10-20 grams is considered a lethal dose. That’s the equivalent of drinking 4.69 gallons of coffee. They say, after all, that what doesn’t kill you, only makes you stronger though, or at least will you keep you up forever!
