On a more serious note, I remember being pretty mind blown in biochem reading about how when you're starving, you exhale acetone (its a byproduct of ketone metabolism or something? idk).
I really wanted to find an anorexic person to see if they could remove their nail polish with their breath.

People on ketogenic diets have the same smell- they call it keto breath. Just find out if there's a Crossfit class at your college and go there, no doubt there's 100 paleotards that reek of acetone there.
 
The coolest fact I learned is how our body adapts to drug use. Our body is like hey, I noticed you are taking a lot of these compounds, let me help you by toning the number of receptors. Once we quit, the receptor numbers go back up. Then we overdose.

Sorry for failing you body 🙁

Paleo is so flipping stupid. I hate it. So much.

Speaking of cancer...

The fact that cancer is actually thousands of different separate diseases and not just a single common disease.

Also, we all have cancer right now. Everyone gets cancer all the time, its just that our immune system destroys most malignant cells before they have the chance to multiply enough to cause end organ damage. By the time a tumor is large enough to be seen on imaging, its already composed of over a billion cells.

Then again, many people don't actually die from the cancers themselves. They die from the side effects of cancer which include a hyper coagulable state and a immune deficient state leading to fatal blood clots and infections.

Its all very interesting.

The healing process of the body. And I'm talking simple stuff. For example, scraped my left shin pretty nasty a few weeks ago. Extreme pain and can barely walk without limping. Week or two later (with the help of platelets, thromboxane, etc) healing process is done and shin is good as new.

Almost as if the body is like "what the fk man, I'm at equilibrium when healthy so get it together". Stuff blows my mind.

Or when your body has a crappy way of healing and you develop keloids
 
Teratomas are pretty disturbing. Espescially the ones with teeth and or hair...

Honestly the only thing I have trouble with is smells. I can look at a lot of nasty things, but sometimes its the smell that I can't get pass.

When I shadowed in the OR for the first time they made me sit on a stool because the last "pre-med" that shadowed passed out at the first whiff of cauterized flesh.

Actually, skin is the largest organ OF the body
The liver is the largest organ IN the body

👍


On a related note, the first organ to be visible on a developing embryo is the spinal cord (er, technically, the groove which will become the spinal cord), while the first organ to be functional is the liver.

Take care of your liver, kids. It's been taking care of you since before your heart started beating.
 
Getting back to skin and keloids though, anyone want to see my little keloid? I think its kinda cute

I've never had a sip of alcohol, so I'd say my liver is in tip top shape!

Does apologizing profusely count as taking care of it?
 
I heard about this in an episode of Mystery Diagnosis (don't judge me!). http://www.ncbi.nlm.nih.gov/pubmed/12394671

Sciatic Endometriosis. Somehow endometrial cells can migrate to the sciatic nerve. The woman in the episode was having extreme leg pain--only during her period--to the point that she couldn't walk. In a nutshell, she was having a period in her leg! And all of the blood was just pooling there and creating scar tissue. 😱

One could say that that was a humerus statement. *ba dum tss*




I'll show myself the door. :whoa:
 
Don't know why but it's always tripped my out that anthrax wants to kill you as quick as possible so it can get back to its spore life in the dirt. It's like you're just in its way of being happy and for that, you must pay.

I love mystery diagnosis! Sometimes it is a bit overdramatic, but I have learned some cool things from that show!
 
I remember my mind being blown when I first learned that I didn't simply breathe in oxygen and have it immediately come out as carbon dioxide. It blew my mind that exhalation is basically my body's exhaust from the food I ate. Just thinking about how well synchronized all of the processes need to be to make that work still blows my mind.

I think it's pretty amazing that we can put someone under general anesthesia, do all sorts of crazy cutting and stuff to their body, and then bring them back into consciousness.

I'm still amazed at the people who were willing to go under when we were still figuring out how to do that.

Yeah but look up the alternative at the time. There are some really crazy paintings from back when they thought pain was an emotion and they just had 6 guys hold you down while they opened up your abdomen. Ill take the experimental drugs too.
