Joints: Crash Course A&P #20

I am so glad that you guys are not five years old! If you were all in, like, kindergarten, the only way I could teach you about your skeletal system would be to sing you that stupid song. You know, “The toe bone’s connected to the foot bone, the foot

When you hear about your “organs,” you probably think of your heart, or your liver, or your lungs. Maybe you picture Captain Nemo playing the organ aboard the Nautilus. Why do they have an organ on a submarine? That is – that doesn’t make any sense. But your first associations

Blood Vessels, Part 1 – Form and Function: Crash Course A&P #27

No doubt about it, your heart is a champion. It electrifies itself, it maintains your blood pressure, it keeps your blood moving, and it’s got like a nice shape you can put some chocolates inside of and give to people you like. But the circulatory system is much, much more

The Heart, Part 2 – Heart Throbs: Crash Course A&P #26

You’ve seen this before in a TV show or a movie. A patient is on the table in the emergency room, bleeding from a stab wound or having ODed on drugs, when suddenly, an alarm goes off and the beep beep beep on the heart monitor flatlines. It’s cardiac arrest,

Your heart, that throbbing, beating muscle, is probably the most iconic organ in your body. No other organ gets its own holiday, or as much radio play. And you’re not likely to get a love note decorated with a kidney or a spleen, or even a brain, which is really

Immune System, Part 1: Crash Course A&P #45

You may not know it, but your body is engaged in a never-ending battle. You are literally covered in staph and strep and e coli, and all sorts of dubious characters that are intent on using you, and your body’s many resources, to feed themselves, find shelter, and reproduce as

In March of 2015, American astronaut Scott Kelly and his Russian colleague Mikhail Kornienko, began an unprecedented mission in space. They began a one-year term of service aboard the International Space Station, the longest tour of duty ever served on the ISS. Now, I imagine there’s all sorts of stuff

The Nervous System, Part 1: Crash Course A&P #8

This morning was a typical morning for me. I woke up thinking about that dream that I keep having about the guy in the sloth suit, and then I got dressed because I was cold, and then I made some toast with butter ‘cause I was hungry, and then I
