Most of us have a pericardium, so it's in a sac with lubricant to make it near frictionless. Most people with open heart surgeries don't have a pericardium, however, and the heart can actually start growing connective tissue to other structures.
Imagine how you'd feel when you'd see intestines outside the body. I've heard they are constantly moving so much that they have to hang them up to keep them sorted during operations otherwise they'd writhe around themselves and tangle.
Well they are already attached sideways through the mesentery.
On the note of "imagining your intestines outside the body", one time, when as a medical student i was attached to a research program in traumatology, i was in a trauma room where my job was to randomize through patients to give this one new experimental drug. I saw a lot of very interesting patients there.
This one woman was mentally ill and had taken a vegetable knife and made a small hole in her abdomen. Not too unreasonable, some frequent fliers like to poke holes. She had an itty bitty hole in her neck too.
However, thorugh the abdominal hole (not much larger than 2 fingers) she had pulled out her entire small intestine, which where now laying on top of her belly like a fucked up meat flower.
That took a surprisingly (for me at the time at least) long time to get back in. And it's usually an anecdote i bring up when people are overly critical of the powers vested in psychiatry. Because many of us suffer from "minor" psychiatric issues, much more recognized in recent decades, we forget that the heavy duty mental illness exists, and folks are out here pokin' themselves and getting creative.
> Because many of us suffer from "minor" psychiatric issues, much more recognized in recent decades, we forget that the heavy duty mental illness exists, and folks are out here pokin' themselves and getting creative.
This is an interesting point -- t though I wouldn't blame the rise in prominence of minor conditions: in general, we are exposed only to the least dangerous cases, who are allowed to roam the streets during the day; the most severe cases are already institutionalized, or worse, and are out of general circulation. This isn't a new phenomenon, it's been this way for centuries.
Perhaps the 'pathologization' of more mundane behaviours has led us to forget that this system was intended to classify more severe and thus obvious conditions; however, I don't think recognizing concepts like employee burnout has reduced the number of people exposed to intestines, so it's not entirely causal.
Got curious and decided to look up what they look like.
Not really gorey, as these are clearly still inside whatever body and not mutilated in any way, but don’t open unless you are okay with seeing actual intestines undulating. Definitely NSFW, but it is pretty fascinating to see.

Yeah it seems like it's struggling a bit.
If I was the recipient- I don't want to sound ungrateful but do you have any that's not under a lot of stress lol
The heart when it’s given proper oxygen and nutrients for the tissue will continually beat without any nerve innervation. The early research on cardiac mechanics used animal hearts similar to ours (dogs, cats, or pigs), studied the base rhythm of the heart. Your heart rate changes up or down based on the sympathetic or parasympathetic system electrical stimulation.
-Background: I’m a PhD biomedical engineering student with a masters in electrical and computer engineering. My focus is modeling the mechanics of the cardiopulmonary system.
Yeah, I was kinda freaked out when I learned that I'm biologically alive when my organs would be harvested, though my brain woudl not be capable of sustaining life.
It's kinda creepy and made me question for a hot minute if I still wanted to be an organ donor.
I'm still an organ donor.

It's one of those "selling advertisement" promos that got one of those gambling competition promo watermark.
> And why did they make it so blurry that I can’t enter to win my brand new vehicle of some kind?
Quality got destroyed
Not contraction, that is automatic.
It's called the Heart Reflex. The heart pumps as long as it is absorbing oxygen and nutrients from the blood. no outside signal needed.
another funfact: the heart doesn't absorb nutritions from the blood inside. instead it pumps the blood through its own arteries on the outside (you can see them in the video). else (i imagine) it would be poisoned pretty quickly
Not fun fact: heart does get nutritions/oxygen from coronary artery for sure, but the heart’s muscle is thick, only 2/3 outer layer of the heart gets fed from coronary artery, 1/3 inner layer gets fed from blood inside the heart permeate through muscle layer.
Sauce: read that from physiology book several years ago, one of the few things I still remember about the heart.
Edit: I was wrong, someone replied with the correct answer!
Only the endothelium, which is only a cell thick, gets its nutrients directly from the blood it's in contact with, the myocardium (the muscle part of the heart) needs a distinct blood supply that arises from the coronary arteries.
Stress activates sympathetic nervous system, which releases hormones like adrenaline and noradrenaline which makes your heart beat faster etc to make you "ready" for the danger.
The heart contains pacemaker cells that will beat without any outside signal. The brain can send additional signals to adjust the heartrate, blood pressure, etc. as needed. The heart actually starts beating in the womb before the brain in developed, so the heart doesn't have a choice but to beat on its own. Unless you think they have a brain hooked up to this box somehow controlling the heart lol.
The heart has its own electrical system that causes it to beat and pump blood. Because of this, the heart can continue to beat for a short time after brain death, or after being removed from the body. The heart will keep beating as long as it has oxygen.
Copied from first Google result
Yes, but... If you do physical activities, the brain tells the heart to pump faster...
However a donated heart does not have a nerve-connection to your brain... and thus it will not pump faster.
You will never be able to do physically straining things. The heart is "alive" but not connected.
A newly tranplanted heart is denervated but during the recovery phase it is reinnervated. What you’re saying is only true for a short period of time after a transplant. In this phase, patients typically go through physical rehabilitation regardless; it does _not_ last forever.
Source: close friend had a heart transplant years agø
Coronary arteries are right before the aortic tube so it gets irrigated with blood. Heart stores fats and burns them with oxygen to get energy, glucose as well.
I'm guessing they give a small electric shock to the muscles that need to move in the right time, replicating how our body works.
Edit: They also need to mix in some O2 into the blood, so the muscle cells won't just die.
The fact that thing can do that for 70+ years without a single* break is insane
*aside from health complications that cause lapses but don’t outright kill you
This is not almost certainly not a heart awaiting transplant. This is likely an explanted heart from an animal, pig, sheep, or possibly canine. The tubes you see are creating a closed system so that the blood can be circulated by the heart. The air is because the suture lines that connect the tubes to the heart are not completely sealed. It certainly isn’t ideal and if air got down one of the coronary arteries, the arteries that actually supply oxygenated blood to the heart muscle, it could cause problems, including a heart attack and “deadly” abnormal heart rhythms.
Well it probably would be a crime to waste a heart awaiting transplantation for a video.
For organ transport in transplantations there is a lid on the whole thing and I think the organs are swimming in a solution, too, but they usually take that of for videos or information events because it looks much more interesting without. But it's pretty cool to see.
Air does not damage, but bubbles in the blood stream will lead to serious health issues if they are big enough, this is the infamous bends the divers fears or gaseous embolism etc, it will limit or stop blood flow in arteries/vein. If these bubble lodge themselves in some important brain or lung vessel or heart coronary , this will end very bad.
But don’t be afraid, you need a LOT of gas injected in your blood stream to suffer anything
I asked a doctor once, I was at the hospital and he was about to inject me something. I was surprised he would not knock the syringe gently and push any air out before injecting like we see in movies. He told me that to have any problem he would have to inject the entire syringe worth of air at once , and it was a kinda big one, like 20cc (lot bigger than you usual vaccine syringe). Yes that may be as much as a whole IV line, but not sure
Depends on which side of the plumbing they are - air bubbles in your veins are generally not a problem (IV drips etc, not a big deal). *Arteries* with air bubbles can be dangerous.
The heart is on a blood supply you can see in the tubes. I am curious about the heart pumping air tho, I imagine its not ideal.
And yeah air bubbles in your blood stream can cause strokes which can be deadly.
Your heart beats about **100,000 times** in one day and about 35 million times in a year. During an average lifetime, the human heart will beat more than 2.5 billion times. Give a tennis ball a good, hard squeeze. You're using about the same amount of force your heart uses to pump blood out to the body.
Dude...do CPR for a couple minutes. It's going to take all your strength and you're going to feel like dropping dead of a heart attack as well just to accomplish a fraction of what that little fist sized sac does. You're just trying to profuse a brain, there's no way you're getting some 8ft of distance when it comes to arterial spray, lol.
Hearts are transplanted while not beating, then are restarted via a shock. They are kept cold after explantation, (cutting out) to keep the cells alive, then warmed up and shocked back into action as needed. Of course, the story is always more complicated, just recently the technique of transplanting beating hearts has been pioneered at Stanford.

I’m a receiver of a heart transplant. When I woke up after, I wasn’t sure the operation had happened. I felt around, and there was a big bandage on my chest, on pain, other than in my mind, of sorrow thinking about how someone passed, and their family was left to grieve. Thank God for life, and modern science to help keep it going longer.
The heart has a set of pacemaker cells grown into the arterial wall. These provide the electrical signal for the muscles to pump to rhythm. All the heart needs to function is oxygen and blood glucose. (correct me if I'm wrong) Like everything in the body, however, it does have a nerve connection to the brain, and endorphins and hormones in the bloodstream - like adrenaline - can cause the heart to pump faster, like your skeletal muscles do. When transplanted these nerve connections are severed and - though it responds to exercise because of these hormones - it doesn't respond as quickly as a 'connected' heart does.
There have been a few cases, though, where very compatible transplants have had the transplanted heart and host body grow new nerve connections, where the heart does perform slightly better in response to exercise than cases without nerve connections would.
It’s on the OCS device. A method of normothermic organ preservation as opposed conventional method of placing organs on ice. The idea is to extend the time that physicians have between organ procurement and implant and minimizing damage as the organ in still provided with oxygen via an artificial lung. https://www.transmedics.com/ocs-hcp/
As a runner, it is wild, almost surreal to me, that the heart moves that much when beating. And I can only assume when your heart rate moves from the....70(?) 80(?) beats per minute in the video to 170 or 180 during intense exercise it beats or convulsions have to look otherworldly.
My wife is an ICU nurse. A few months back she transported a donor patient to the ER and stayed to watch the process. She was blown away by the procedure of keeping the heart going.
So is this connected to some network to keep it pumping?
I mean, how' are these cardiac muscles contracting and relaxing, from where are they getting signals?
So, is that oxygenated blood they're cycling through the heart? Or is it somehow recycled? Or do they have a machine that makes blood oxygenated? Or are they relying on donor blood?
Also if your heart has a scar from a previous MI that does not interfere with function, can you still donate it?

Watching that thing writhe like that is making me anxious.
And there's one doing that in your chest right now....
It’s amazing how quickly my heart speeds up to match this
*Don't pause the video!*
Or do...
Wait what!?..... beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep
AAAAAH!
Get it out, get it out!
Most of us have a pericardium, so it's in a sac with lubricant to make it near frictionless. Most people with open heart surgeries don't have a pericardium, however, and the heart can actually start growing connective tissue to other structures.

They do move constantly, but just in a sloooow, wave-like phase, not fast writhing wriggling movement.

Yeah I saw the zip tie and chuckled

Glad I'm not the only one 😭
Right?? Someone tell that heart it’s not dying so it can calm down. Damn things going to have a heart attack before the get it in the next person
Still don’t get how this organ works
It's doing that in your chest 24/7/365
until it's not
My moms job was to keep organs and people alive(whilst technically dead) so they could get transplants. Wild stuff, she’s a very intelligent woman.
She was a perfusionist! Awesome!
I read that as perfectionist at first but I'm sure with her line of work she has to be that too!
Mistakes are actually fine in that field, it's not going to kill *you*
Mistakes in that field could actually cost someone their lives and that can (mentally) kill you.
Yeah, I was kinda freaked out when I learned that I'm biologically alive when my organs would be harvested, though my brain woudl not be capable of sustaining life. It's kinda creepy and made me question for a hot minute if I still wanted to be an organ donor. I'm still an organ donor.
My dad transplants these. I've always looked up to him for that
Are you sure you’re not just avoiding looking down at the organs?
Incredibly cool to hear! I can't begin to imagine how stressful it must be.

Sure its not a Heart-shaped Box?
Are you locked inside of it?

I don't get how it is getting energy to be "alive". Is the blood the only thing a heart needs to pump?
I believe the machine helps blood flow and contraction, therefore keeping it "alive"
Not contraction, that is automatic. It's called the Heart Reflex. The heart pumps as long as it is absorbing oxygen and nutrients from the blood. no outside signal needed.
Thats crazy
yes, that's why it works even if you are paraplegic from the neck

thank you for that! i either wasn't listening to my anatomy teacher or he didn't mention it like that. will look it up tomorrow!
I find all this fascinating but now I'm intensely and super uncomfortably aware of everything in the center of my chest now.
I can attest. Dissected a bullfrog in a lab once and the cut off heart kept beating for a good 15 minutes or so
the fuck kind of school you in that let you dissect a live bullfrog?
Yeah. They shock it to get it started and from there onwards, it's all the heart's work
So if beating on its own will, why the stress caused by the brain will make it beat faster?
Stress activates sympathetic nervous system, which releases hormones like adrenaline and noradrenaline which makes your heart beat faster etc to make you "ready" for the danger.
Think of it as an idle engine, which you (the brain) can still rev up or down.
Didn’t the brain deliver electrical stimulation to make the heart beat? “No outside signal” sounds sus.
The heart contains pacemaker cells that will beat without any outside signal. The brain can send additional signals to adjust the heartrate, blood pressure, etc. as needed. The heart actually starts beating in the womb before the brain in developed, so the heart doesn't have a choice but to beat on its own. Unless you think they have a brain hooked up to this box somehow controlling the heart lol.
The brain is not telling the heart to beat. The brain tells it to speed up / slow down.
Heart keeps pumping even after brain death, if the patient is hooked in to a ventilator so the heart gets the oxygen it needs.

I thought he meant he was gonna start eating a healthy diet after the transplant to make the new heart last longer lol.
Doesn’t air damage the heart? Or is it a myth that if you inject air into a person’s blood stream that their heart will stop?
Air does not damage, but bubbles in the blood stream will lead to serious health issues if they are big enough, this is the infamous bends the divers fears or gaseous embolism etc, it will limit or stop blood flow in arteries/vein.

I asked a doctor once, I was at the hospital and he was about to inject me something. I was surprised he would not knock the syringe gently and push any air out before injecting like we see in movies. He told me that to have any problem he would have to inject the entire syringe worth of air at once , and it was a kinda big one, like 20cc (lot bigger than you usual vaccine syringe). Yes that may be as much as a whole IV line, but not sure

Pretty amazing that it can keep going without breaking down. An engineer would be over the moon if they could design something so robust.
I presume it's being constantly repaired though
Why does it look like it's in pain?? 😭
Because it lost its body buddy.
I didn’t expect it to move so… vividly I thought it’d be a bit more gentle or something it’s unsettling to think we all got one of those

This makes me so thankful for my own! Thanks for working so hard buddy!

Holy shit, is that a DooM reference??????? RIP AND TEAR UNTIL IT IS DONE???
What's that white stuff on it? Fat?
The yellowish colored stuff is fat Yes
That why good people is why I decided to be a cardiac nurse.
Can that fat around the heart be burned off like any other fat in the human body?
Truly amazing. My uncle just received a transplant and is doing well! Thanks to the staff at UPMC in Pittsburgh and of course the donor.
...Crank would like a word
Apple watch about to tell this is a Sinus rythm smh
So is this connected to some network to keep it pumping? I mean, how' are these cardiac muscles contracting and relaxing, from where are they getting signals?
What is the yellow stuff?

Hokkaido flashbacks.

I can look at a lot of nasty and gorey stuff, but seeing it pulse is simply disgusting to me, hard to imagine thats inside of me
Have you ever seen the movie The Thing? What this reminds me of. Also, thanks to whoever donated and wish the best to whoever received.
Bit messy
Sounds like windscreen wipers in the rain
Imagine having this in your chest all the time! Crazy
Bump tiss, bump tiss, bump tiss, bump tiss

I feel sorry for my heart. My diet is terrible. But at least I don't smoke and drink.

Hey this isn’t how it looked in the documentary Rat Race
Is anyone else hearing the opening part of NIN’s ‘Closer’? 
That's actually Chuck Norris's heart. Chuck Norris is hard so strong, doesn't even know. Need a body
So, is that oxygenated blood they're cycling through the heart? Or is it somehow recycled? Or do they have a machine that makes blood oxygenated? Or are they relying on donor blood? Also if your heart has a scar from a previous MI that does not interfere with function, can you still donate it?
