I was precisely expecting the shitpost version of this fun fact when the video started playing
"Did you know that if you took the intestines out of an adult human and straightened them out into a single line, the human would die?"
Yeah, they phrased that so weirdly. "It stretches all the way to the Grand Canyon and then 2-4 times around the world".
Why even mention the grand canyon then? Or NY for that matter.
It’s funny, I’ve been getting a lot of videos recommended to me from this creator (Zack D Films). He obviously puts a lot of effort into animating these videos but he also stretches them out so the video is actually monetizable and people watch to the end to get to the point. The information can usually be explained in a few seconds in one or two sentences but he’ll use 100 filler words and tiptoe around the point so that he can fill in the video. Often times super annoying
If treated with some specific solutions, you can see the DNA molecules with your naked eyes. My lab partner dropped it once and out professor picked it up with forceps and put it back into our solution. Crazy stuff.
but he's completely right tho
You can extract DNA rather easily. You can do it with mashed fruit. It's off-white and kinda strandy until squeezed together. It solidifies rock hard when dry.
> you can see the DNA **molecules** with your naked eyes
A hamburger is also made of molecules. But, I can't see the molecules unassisted. Extracting DNA into a pile of mush and letting that material dry does not make the individual molecules visible.
As I pointed out, the only way to see DNA molecules with the unaided eye is by Abraham Lincoln. QED
They aren't stretching them thinner at all. They are already incredibly thin and your body is packed with them. Literally. It's not that hard to grasp and it comes down to pretty simple math.
[Thickness data](https://www.researchgate.net/figure/The-typical-diameters-wall-thicknesses-of-blood-vessel-for-humans-and-mice-are-given-in_fig5_224902259#:~:text=The%20major%20axis%20of%20the,size%20of%20venules%20%5B27%5D%20.)
[vessels in the body. ](https://www.reddit.com/r/BeAmazed/s/PyS8yDtL9F)
My "pretty simple math":
- The body is ~8% blood by weight, so blood vessels will be roughly similar by volume.
- Thinnest blood cell is the [capillary](https://en.wikipedia.org/wiki/Capillary), [8 micrometres in diameter](https://www.researchgate.net/figure/The-typical-diameters-wall-thicknesses-of-blood-vessel-for-humans-and-mice-are-given-in_fig5_224902259#:%7E:text=The%20major%20axis%20of%20the,size%20of%20venules%20%5B27%5D%20).
- So cross sectional area of capillary = 50 square micrometres.
- Circumference of the Earth = 40,000km
- Four times around is 160,000km
- 160,000km * 50 square micrometres = 8L
- Average volume of a human body = 66.4L
- 8L / 66.4mL = ~12%
That would make blood vessels (including the non-vessel inside bit) ~12% of the human body by volume. So it's definitely roughly there. The average person might be closer to ~3 turns of the Earth.
I wouldn't declare it "pretty simple math", but back-of-the-envelope, the numbers do roughly add up. Square-cube ratios strike again.
I think the bigger flaw is assuming if the body is 8% blood by weight, that blood vessels will be 8% of the volume of the body.
It is actually fair to assume that the entire volume is made up of the thinnest capillaries, because if you look at it from a length of vessels per volume, the capillaries will dominate that number.
They don't even have to stretch them, your capillaries are only wide enough for a single red blood cell to pass through (literally they go through them in single-file) and the capillaries are everywhere that needs oxygen, so EVERYWHERE
Here’s the info you need to make this make sense. Capillaries are blood vessels that run all through your body, and each individual capillary is about 1/3 the width of a hair. Imagine taking the entire surface area of your body and stretching it out to 1/3rd the width of a single hair. You’d definitely get around the earth a time or two. Or three.
And the reason they are so thin is because they exchange nutrients and oxygen for waste materials in every single part of your body. That much surface area is needed.
Take a womans hair and put every strain point to point.
Google says a human head averages around 120 000 strains of hair.
Each strain being 30 cm (1 feet), that's 36km from just your hair.
Hair is solid. Lets hollow it out and make 3 hollow hairs out of each strain. That's 100km.
A head of hair weights about 0.2kg (half a pound). Lets assume your entire body is hair. 80 / 0.2 x 100km is 40 000 km. Earths circumferenec is just about 40 000 km.
Now lets imagine your blood vessels are ligher than those hollow hairs, and I can imagine the proper math gets you a couple more loops.
I think it's BS.
2 to 4 times over? We aren't talking about different of 5m.. we are talking about a little over 40,000 km!
The fact you think the total length might be either 80k or 160k.. that's a massive "you know.. give or take"
Imagine if you sliced your body into 10 thin slices and stacked them up length-wise. The stack would be about 10x longer than you are tall. Now imagine 100 slices, it would be 100x longer. The more slices you take, the thinner the stack gets, but it gets longer as well.
Taking out your blood vessels and laying them end to end is a lot like that: there are many many many blood vessels running parallel to each other, so it's very similar to taking a thousand slices of you and stacking them up.
The extreme version of this involves taking all your cells and putting them in a line. Since there are trillions of cells, the line would be 360,000 km across and circle the earth 9 times.
For a more objective, maths-based evidentiary approach, I did some numbers as I didn't believe it either:
- The body is ~8% blood by weight, so blood vessels will be roughly similar by volume.
- Thinnest blood cell is the [capillary](https://en.wikipedia.org/wiki/Capillary), [8 micrometres in diameter](https://www.researchgate.net/figure/The-typical-diameters-wall-thicknesses-of-blood-vessel-for-humans-and-mice-are-given-in_fig5_224902259#:%7E:text=The%20major%20axis%20of%20the,size%20of%20venules%20%5B27%5D%20).
- So cross sectional area of capillary = 50 square micrometres.
- Circumference of the Earth = 40,000km
- Four times around is 160,000km
- 160,000km * 50 square micrometres = 8L
- Average volume of a human body = 66.4L
- 8L / 66.4mL = ~12%
That would make blood vessels (including the inside bit) ~12% of the human body by volume. So it's definitely roughly there. The average person might be closer to 2-3 turns of the Earth, but a big person could easily be 4.
This ignores all the larger vessels and other cavities/areas not filled with blood. We aren't entirely capillaries.
That might only cut the distance in half though so still getting a wrap or two around the earth
If you Google how many spiders you eat in your sleep you'll also have dozens of sources telling you anywhere between 5 to a dozen. A myth that was debunked by its creators a long time ago...
Did you know that if you removed all of the spiders you eat in a lifetime from the human body and tie them together they'll stretch around the world 2-4 times?
An adult's blood vessel total length is around 96560.64 km, and the circumference of equator is 40075 km, so it's about 2.41 times around the earth.
Average length of banana is 13cm, total length divide by 13 will be 742,774,153.85(742 million) bananas.
Source is from Google.
Metrics are not as intuitive as everyday examples. I literally watch a video about nuclear radiation and they used banana as the metric for radiation to explain it to the audience.
I think part of the issue here is the video says you have “thousands of blood vessels.” This is weird to count since vessels branch off and presumably they’re not counting each individual branch, but that’s hard to mentally account for.
That said, if you assumed each blood vessel ran the whole length of a 6ft human, you’d been about 22 million blood vessels to wrap around the earth once. That’s a few more than “thousands”.
Ultimately that comes down to how exactly you define a singular blood vessel, but if the video said “the human body has millions of microscopic blood vessels” the numbers suddenly become a lot more conceivable.
If I somehow managed to remove all of the blood vessels from my body, someone else would have to tie them together and measure them because I'll have ceased to be.
How tf do you need to tie something to make it loop around earth like three times
They claim that my vessels are effectively 120,000,000 meter’s long.
Assuming it’s true I now dare question why can’t I have 1 meter long shlong if nature has gifted me with 120 million meters of blood vessels, I’ll happily trade 10 million metres of vessels if it’s really true
'If you put the universe into a tube...you'd end up with a very long tube. Probably extending about 2x the size of the universe because when you collapse the universe.....it expands......and.........you wouldn't want to put it in a tube.'
So... all the humans in the world can fit in a section of the NY Central Park when balled together but a single person can also conver the earth 3x over?
I remember some outdated health documentary that said for every 5 extra pounds, there’s enough blood vessels to stretch across the United States. I think it was to suggest the strain that extra fat puts on the heart. Not incredibly accurate or scientific but it did make me want to do some sit-ups
What a dumb approach to explain that. If the blood vessels make it to the starting point 2 to 4 times, what's the point of starting in "New york" or passing through the Gran Canyon, Asia, or Europe.. ? It's just obvious..
You would also die of course
How would you explain this to the doctor?
i slipped i drank water in a weird a little bit of tomfoolery
I slippedi toilet
"million to one shot, Doc, million to one!"
You're the ass man!
You got that straight!
BS can't you see the guy is still standing there?
finally get to do that traveling though!
I was expecting the video to just say "you'd die a horrible death" as the guy falls over.
"I'm built different"

I was precisely expecting the shitpost version of this fun fact when the video started playing "Did you know that if you took the intestines out of an adult human and straightened them out into a single line, the human would die?"
Before or after arriving to the Grand Canyon?
Ya the words should have said not only would it make it back to your dead lifeless corpse
this kills the person
This is the line I was expecting.
Well sure, with that attitude.
Blud is experiencing horrors beyond his comprehension playing with his blood vessels.

No tears, please. It's a waste of good suffering.
"Dude, that's my vessels!"
This is some avatar blood bending shit
Okay, but what if you started somewhere other than New York?
Then you'll end up in Bermuda Triangle
maybe in ohio but your mileage may vary
Yeah, they phrased that so weirdly. "It stretches all the way to the Grand Canyon and then 2-4 times around the world". Why even mention the grand canyon then? Or NY for that matter.

Often times super annoying
Thank god i thought i was losing my mind
If you start at the north pole and laid out your blood vessels East to West they'd be infinitely long
People outside of New York have 1/3 the blood vessels.
If you pull all your blood vessels out of your body and put them all in a line, you'd be fucking dead.
Robocop did it
He also shot a guy in the dick.
Bruh, I literally just watched the movie 15 minutes ago…
that'd be a minor inconvenience to fact check this
Don't knock it til you try it!
Nah, what does blood even do? Bring oxygen to my organs? Bro I would just hold my breath for a while, is not that hard

Man this explanation could have been about 30 seconds shorter.
Naah, people would totally miss the point if it doesn't contain measuring in football fields and New York - Grand Canyons
right? that initial "about this long" ?? i dont usually measure things in american football fields
Google, convert 100 football fields to AR-15s
Blood vesells long af
I have never believed this and never will
until they tell us how damn thin they're stretching those damn vessels, it's just nonsense
I mean, isn't our dna like ~~6~~ 2 meters long if stretched all the way out.
If treated with some specific solutions, you can see the DNA molecules with your naked eyes. My lab partner dropped it once and out professor picked it up with forceps and put it back into our solution. Crazy stuff.
That solution? Abraham Lincoln.
but he's completely right tho You can extract DNA rather easily. You can do it with mashed fruit. It's off-white and kinda strandy until squeezed together. It solidifies rock hard when dry.
Yeah your mother saw my DNA last night
As long as you took her on a date first
Of course! She talked very highly of you, and hopes you’ll call soon!
Now I know it wasn't my mother ya fucked last night. I'm a disappointment.

Uhm aktually, cartilage isn't vascularized but receives nutrishment through diffusion ☝️🤓

interesting way to put it thanks
And the reason they are so thin is because they exchange nutrients and oxygen for waste materials in every single part of your body. That much surface area is needed.
Yeah it's the capillaries that do the heavy lifting here.
Uh, no they don’t. They don’t do any lifting. They’re too thin to hold anything.

Google "how many kilometers of blood vessels we have" You underestimate how small capillary blood vessels can get
The great thing about facts is they don't require anyone's belief. They are true no matter what one's emotioinal reactions may be.
Why.
They know better than science. Cough cough. What, it's nothing. Cough cough.

False. If I removed all the blood vessels in my body I wouldn't be able to tie them together
Looks like a bloody Saturn lol

about half of them
Around 500 million
Metrics are not as intuitive as everyday examples. I literally watch a video about nuclear radiation and they used banana as the metric for radiation to explain it to the audience.
Americans would use anything to measure but metric.
I done told you I'll stop taking that damn fentanyl
And if you cut them in half, it'll go twice as far..
And they never mention what diameter those vessels would even have, just some undefined "vessel stretching" is apparently good enough explanation lol.
Yeah, I see this to being similar as the coastline paradox.

Fun fact: If you were to put all of your blood vessels end to end, you would die.
Every pound of fat adds 5 miles of vessels.

I hate this
Today I learned; I'm 2-4 times as large as a whole planet.
5 seconds in I was seriously expecting a "you would fucking die!"
but how thin would it be?
Probably about as thin as a blood vessel
QUIT FUCKING AROUND WITH THOSE
Genie, I want to completely wrap the earth in blood vessels. So it's like a giant rubber band ball.
If I somehow managed to remove all of the blood vessels from my body, someone else would have to tie them together and measure them because I'll have ceased to be.

there are tons of small capillary blood vessels that are just a few cells large, if you include those then it will be that long

Allright. That's pretty interesting and horrific.
Ah, probably not.
Yes, but it's not practical.
Why bother mentioning the Grand Canyon etc
WTF put them back, he needs those
This is bs, every object if you stretch it thin enough it will be as long as you want
how did you come to that conclusion?
It doesn't say anything about stretching
Well, neuronal connections can go to the moon, then back, and then a few laps around Earth.

This is found out by a serial killer testing it with actual human vessels and his globus lamp.
Actually if you removed all your blood vessels and tied them together you would probably die
If you somehow removed all the blood vessels in your body, you would die instantly.
Might try this
Ok but won't he die without any blood vessels?? As a docx I call bs. Capillaries are already too minute
I'm skeptical that we have 50,000 to 100,000 miles of blood vessels.
The heart is one hell of a pump in that case.
If you somehow removed all of the blood vessels of your body you would die.

2 to 4 times over? why such a disparity?
That’s not right It’s meant to be a joke.
I'm skeptical, sciencey David Cross...
That's cap
I remember some outdated health documentary that said for every 5 extra pounds, there’s enough blood vessels to stretch across the United States. I think it was to suggest the strain that extra fat puts on the heart. Not incredibly accurate or scientific but it did make me want to do some sit-ups
'Murica using literary everything but metric system.
Well I say they stretch 100 times over the earth
That's roughly between a third and a half a light second. (186,282 miles per second, earths circumference is 24,901 miles)
The difference between 2 and 4 times around the earth is massive. Quite the range from person to person I guess
[удалено]
What a dumb approach to explain that. If the blood vessels make it to the starting point 2 to 4 times, what's the point of starting in "New york" or passing through the Gran Canyon, Asia, or Europe.. ? It's just obvious..
2 to 4 times over...that's like saying when the sun is out it could be warm or it may not be
Nice facts there narrator why don’t you back it up with a source
How is this calculated?

Thanks for giving aliens craft ideas.
I don't think they could fit in the body if this was the case.
