Just got my tickets — 8th row, bitches!
Reblog. Don’t repost.
THEY HAVE STOLEN MY GIFS AND IT MAKES ME ANGRY THAT THEY GOT PRAZED
SO THANK YOU
They’ve stolen mine too, asked them to stop/give credit/take it down, they didn’t.
Oh boy, they posted two of my gifs TODAY without credit (from my Rhett & Link blog). And their FAQ is bullshit. “If I have reposted a GIF of yours ask nicely and I will 100% remove it or give credit.”
Or, how about you don’t make it everyone else’s responsibility to police your blog, and instead just reblog instead of repost in the first place?
I really feel like John’s premiere somehow overshadowed mine.
NO STOP THIS IS THE MOST UNCOMFORTABLE I HAVE EVER BEEN
Hey Wil, would you ever do an MDK with Hannah Hart? I'd watch the hell out of that...
Yeah, we’re friends, and we’ve talked about it. We just have to make the scheduling work out.
THIS WOULD BE SO AWESOME.
Twin Peaks + Welcome to Night Vale
This is brilliant.
Why do veins stick out, but not arteries?
Arteries are pressurized, much more than veins. Veins are like a reservoir of blood waiting for your heart to pull it in and pressurize it. Arteries are like fire hoses of blood. Lots of positive pressure so that it can be pushed into all of the tiny crevices where your body needs oxygen.
Now you might think that this means arteries would bulge out more than veins. And indeed, if they were there, they would. But because your arteries are fire hoses of blood they tend to be buried quite deeply in your tissues, behind layers of muscle and fat so that, if you scrape yourself, you don’t become a human blood fountain.
Below is a cross section of the human forearm.
Two more questions might have popped up as you read this…and I’m going to answer those as well.
1. Why do veins bulge out if they aren’t pressurized?
Well, they are pressurized…just mostly by gravity. If you see the veins on your hand standing out, just lift them above your head and watch as all that blood drains out of the long, skinny balloons of vascular tissue that run all throughout your body.
2. Why is any of the circulatory system near the surface of the skin…seems dangerous.
Cooling! The veins you see near the surface of your skin are “superficial veins.” They don’t actually carry that much blood…just enough so that, when you’re hot and sweating, they can dump some of your body’s heat into the environment to prevent you from overheating.
When you’re cold, those veins constrict and much less blood moves into them, allowing you to conserve heat.
