We all know that the human body is very complex.
But even with all the recorded and available science, there are certain things about our bodies that continue to elude us, and medical experts can still get stumped about how the human form reacts unpredictably.
Curious to discover some of the mystifying yet unsettling truths about our anatomy, Redditor Hot_Banana_Ice-cream asked:
"What is a creepy fact about the human body?"
Now, observe this.
Visceral Reaction
"If you wear glasses which vertically inverts your vision long enough, your brain will correct it, and you'll see things normal. But when your take those glasses off, everything will look upside-down again until brain recalibrates again."

Brain Assessment
"Our brain filters out a lot of what we see along with just straight making sh*t up based on extrapolation."

The Experiment
"My favorite is the blind spot at the center of each eye, where the optic nerve is."
"A lot of people don't even know it exists, and even if they do, it is bigger than people often think."
"And it's also really easy to demonstrate to people if you know how. It's one of my favorite bar tricks - all you need is a pen and a napkin to draw a cross and a dot."

Alternate demo: https://faculty.washington.edu/chudler/chvision.html
"Edit: If it doesn't work, you're doing something wrong - not getting close enough, the image is too small on your phone, you're not closing the correct eye or not keeping your gaze fixed on the cross."
"It isn't because you don't have a blind spot. Unless you're a squid, you have a blind spot. All vertebrates have them."

The workings of our innards are out of this world.
The intestines are covered by a double "fleece" of peritoneum. See it like a blanket.
When your intestines get damaged for whatever reason, this blanket starts moving out of itself and crawling upwards towards the place which has the injury. It will stay there until the injury is recovered. And then move on again.
Maybe not the most creepy fact, but definitely interesting in my opinion.
Do Do That Doo-Doo
"We don't just have one anal sphincter. When poo comes along it passes another inner sphincter which isn't under voluntary control."
"Sensory cells can detect whether you're about to pass gas or solid. From toddler age on, you can decide to go or not to go. If the time isn't right (e.g. at a friend's house or no toilet nearby), the inner sphincter can push the poo back and store it there for later."
"That's why sometimes if you need to do a number two but don't go, the urge goes away after about 20 minutes later. (But seriously, go if you can. Constipation risk.)"
"Gas can't be pushed back so easily, so we sometimes toot by accident when moving or engaging the core."

The Same Lining
"The inside of your cheek and your rectum are lined by the same type of tissue."

You don't always have control of your body.
Taste Of Curiosity
"The front of your tongue is curious, constantly patrolling, and autonomous. It chases the dentist around your mouth and you aren’t even aware of it. So embarrassing and weird/creepy."
– AdeleBerncastel
Licking Partner
"In dental school, I learned this fact when practicing taking impressions on each other. My buddy’s tongue kept licking my finger. I asked him to quit licking me, and he was like 'I can’t help it!' And then we switched places and my tongue wouldn’t leave him alone.And for those of you that don’t think your tongue does this: some of you are right. But the majority of you just think your tongue is behaving, but it is all over the place without you even knowing."

Dancing With The Dead
"Bodies will move as they’re coming out of rigor. I’ve been bumped by a few (I’m a coroner). Bodies can also make sounds as the remaining air/ gas leaves… 2am in the morgue and I thought I was in COD zombies."
– Jar-JarShotFirst69
Wonder of wonders.
The Only Way Out
"When you get laser tattoo removal the ink doesn’t disappear, you pee it out."
"Your body’s immune system breaks down the pigments of ink and it flows in your blood stream, gets processed through your kidneys, then you pee out the ink."
– Fine_wonderland
Our soul-containing vessel is a mysterious wonder unique to us.
We should do whatever it takes to take great care of it because it's the only one we've got.
If we don't, they might turn on us.
We are complicated vessels that emit all kinds of liquids and other substances depending on the circumstances–the usual suspects being blood when we're injured, sweat when we hit the gym and tears when our emotions get the better of us.
Of course, that's not all we expel from our bodies.
But anything beyond what is mentioned above is not something we should ever have to experience or envision.
Strangers online did not hold back when Redditor Silveo02 specifically asked:
"What is the nastiest thing you’ve ever seen come out of a human body?"
When your body fights off infection, it produces slimy nightmares.
Airborne Goo
"I was congested really bad one morning, I kept coughing to try to hack it out as one does, and right as I was getting out of my car at work, I sneezed something fierce, and a mass of bloody mucus and what I hope were boogers shot out of my nose."
"It was so large that my face felt empty, like I had lost part of my body. I wasn’t even disgusted, just intrigued and shocked, and relieved, but also stressed bc I thought I was missing some brain matter."
– InspectorGajina
Clearing The Pipes
"About ten years ago I had an awful sinus infection and sneezed out what I can only describe as a bloody tubular snot cast of my entire nostril. It felt glorious and I marveled at how something so large and disgusting could come out of my nose."
– MyTapewormToldMeSo
A Staph Infection
"My son got MRSA in his knee somehow when he was like 6. Draining the wound was vomitous."
– amalgaman
Swollen Upper Lip
"I had MRSA in my upper lip from chucking raw clams We'd use to farm in bags. The thing about raw clams is wasps and hornets just can't get enough of the soft meat and packs of 8 of them will fight you for a clam. Needless to say getting stung is one thing but getting stung by a wasp or hornet covered in raw clam is a infection nearly for sure."
"My upper lip swelled about 6 to 8 times or size and had to be juiced like a meaty toothpaste tube."
"I got the lucky end cuz my old step-dad would get stung dozens of times and had infections across the back of his whole head from em."
– accelis
Untreated dental issues can lead to seriously disgusting results.
Leave It To The Dentists
"Severe tooth abscess......whole jaw was swollen."
"Pushed my cheek hard until it popped and blood and puss filled about half my mouth. It hurt so badly that I got tunnel vision, started to black out, and almost vomited at the same time."
"'Do it yourself dentistry'.....don't do it kids."
– Crazy_Fun_3455
Artwork On The Mirror
"Yeah, I had the same thing happen, except it was a top tooth, and the whole roof of my mouth was puffy and sagging like the roof of an 86 Dodge Caravan."
"I had to travel for work, and was in a ton of pain. I had a layover in Denver, and went to the bathroom to check it out."
"I'm standing in front of the mirror, and press my thumb on the roof of my mouth. Green pus and blood erupts from around my front tooth and sprays all over the mirror. The smell was overwhelming, as was the pain."
"The guy who was washing his hands next to me couldn't take it- he immediately vomited in the sink and bailed out of the bathroom. I quickly tried to clean up as best as I could and made my way out of the carnage as well."
"Once that was gone I did feel a lot better."
"Edit: To the mustachioed gentlemen in the Denver airport, if you're reading this, I'm really sorry. You didn't need to see that- I had no idea it was going to happen, and I hope this hasn't affected you beyond your initial chunder."
– OnionMiasma
The One That Stayed Behind
"When I was in college I interned with a dentist and he would do a free dental day where transients and stuff could come in and get dental work done."
"One guy came in complaining of jaw pain, turns out that he had a baby tooth that never came out that got engulfed by an adult tooth that then pressed the baby tooth into his jaw. The tooth rotted and festered underneath the permanent tooth."
"The dentist extracted the permanent tooth and when he did it shot out a brown fluid that smelled exactly like death, followed by the baby tooth pieces. I pride myself on being pretty calm but when this happened I had to leave the room and vomit."
"It pretty much turned me off to wanting to be a dentist."
– itsthattedguy
These patients endured intense pain and suffering they couldn't soon forget.
Burrowed Friends
"I’m a dermatological surgical technician for skin cancer removal, aka Mohs. After removing a cancer from an older gentleman’s leg, we stitched him up and applied steri strips (which fall off by themselves within a week) so no wound care would be needed. The pressure dressing on top of the steris would simply have to be removed in a day or two."
"This older gentleman came back to the office 1 month after his surgery complaining of an odor coming from his post surgery wound. When he arrived, the 'odor' was far worse than expected. Employees of the office were gagging."
"Also, keep in mind, in dermatology we deal with smelly things such as cysts on the regular. Odor typically doesn’t bother us. Upon further examination, we realize this patient never took off our original dressing. Once the doctor came in and removed the dressing we saw anywhere from 60-100 maggots burrowed in this man’s open wound. All of which had to be manually extracted."
"Just another maggot Monday."
– Alexiwitchwork
Birthing A Bug
"I seen a fully grown botfly get removed from someone's arm while doing my college co-op at my local hospital."
– SnowyInuk
No, Thank You
"My daughter had pinworms when she was in kindergarten. For those who don’t know, they are small worms that crawl out of the anus and lay eggs, then crawl back inside. It was like something out of a horror movie."
– rupret1
Projectile Pus
"Lancing one of those diabetic cysts and what came out was a mixture of blood, pus and some thick black, what looked like a burnt French fry. At the end the last bit of pressure shot out everything and hit the wall. Smelled like a copper penny and what your cast smells like after a week or so."
– donutdong
After The C-Section
"A week after leaving the hospital from having my son via C-section, I was in horrific, screaming pain. Ended up in the ER, where it was discovered that I had a softball sized abscess directly behind the C-section cut. They needed to open me back up and get me cleaned out, but didn't want all that nasty sh*t to just spill out of me. So they put a tube in me and attached it to a bag to drain it. So I spent a day in a hospital bed with this clear bag filled with putrid, brown, rotting gunk attached to me. It smelled so bad, and looked even worse. Why did the bag have to be clear??? It's been 15 years, and thinking about it makes me gag."
– sallyface
The Attached "Gunk"
"I had a drain similar to yours after my appendix surgery site got infected, but I had mine on for several days. I honestly don’t know why they had to make it clear, the gunk was so damn nasty, but that wasn’t the worst part. That was the fact that since it was attached to me, I could feel how warm the gunk was and it made me feel so damn sick whenever i felt it."
– lonely_catt
Poor Elderly Resident
"A seriously compacted resident in a nursing home I worked at had stool coming out of every orifice. This poor man was throwing up stool it was horrifying. He passed shortly after that."
– AlienGoddess91
While many of these people experienced excruciating pain, the lingering memory of those moments appeared to be what they smelled as a result of their various infections being the worst.
Horrific, indeed.

Beta Testing
Season 3 Nbc GIF by The OfficeGiphy"The Male reproductive system."
"I mean, who thought this up? The most important part of the system, the testicles, are positioned outside the man’s body, inside a fleshy pouch, with virtually no protection from the elements or worse, physical injury."
"Women’s ovaries are deep inside her body, protected by surrounding muscles."
"Men have this floppy bag that has zero support - they get crushed when you ride a bicycle or sit in a chair, get caught in your zipper and ache like hell at the smallest impact."
"And you’ll tell me that sperm cells need to be kept cooler than the 98.6F body temperature of the human body? Why? Who thought that up?"
"I think what happened was that God created man without a reproductive system but after He created woman, the man’s body had to be redesigned to accommodate a reproductive system."
"I think the design never got past the beta testing phase and went into production as is, flaws and all. And so here we are."
- Keithninety
"Testicles so easily hurt or injured. Why aren't they on the inside instead of being exposed?"
- Back2Bach
"Instead of designing new sperm cells evolution said: F*ck it let’s hang them outside to keep them cool and remind you how important they are by making them really sensitive to pain."

How high was God or whoever when they designed the human body? Clearly they needed a crash course in anatomy.
The body is amazing and resilient, but it can also be a hot mess.
Why are so many areas susceptible to pain? Like, one bad fall on a knee and you could be hobbled for life.
They should be more bulletproof. And the eyes, why so fragile when a wild eyelash gets caught in a blink?
So many questions. If the body was intended to last ten decades or so, it should be a bit more bionic.
Redditor MrBowls wanted to get into details about anatomy and it's issues, they asked:
"What’s the worst designed part of the human body?"
I have pain everywhere. Just because I'm not twenty anymore doesn't mean my body gets to just give in. I know I could help more with that issue, but I feel like my design should be more automatically durable.

The Nerve
"The sciatic nerve routing. Going through the periformis muscle was a bad idea." ~ Sleepdprived
"Just FYI: actually passing through the muscle is an anatomical variant. For the majority of people, the nerve just travels alongside the muscle. Still, that variant is a... uh, pain in the butt." ~ EauEwe
"I'm currently experiencing sciatica right now. It's a nerve being pinched by your spine or muscle in the lower back. The best way I can explain is like a scalpel scraping off your bone marrow throughout your entire leg 24/7."
"It's physically and mentally excruciating so much so that people who suffer from it would rather have their entire leg amputated than live through it. And the thing is this is not an uncommon medical condition. Since the cause is usually a spinal injury, it takes way longer to recover than other injuries, so you're pretty much sleep deprived and exhausted from the pain at every moment until it resides. I'm 25 right now and my first sciatic episode started when I was 21" ~ psyatica

"He also had teeth growing sideways in his gums which torqued his other teeth. It took 2.5 years to get him prepped for orthodontics and then he was in braces for another 5 years after that. Worth it though, he looks like a Colgate commercial now." ~ justuselotion

"The elbow. Why the f**k is there a nerve that's so exposed, when you hit it at just the right spot it sends a jolt down your arm?!" ~ hikoboshi_sama
"It’s not just one nerve. You’re talking about the brachial plexus. It’s a bundle of nerves that come from your spine and innervates all the muscles in your arm. That’s why stingers hurt so much, it’s taking out every nerve."
"It’s also a good site for nerve blocks when you have upper limb surgery because you can disable the arm and reduce post operative pain by applying anaesthesia around the nerve roots. Also, in the case of brachial plexus avulsions, you lose all function permanently. And on that note, nerve injuries are freaking crap. We should be able to regenerate them more easily and quickly." ~ ShibuRigged
Cardboard
"Knees are a good idea, but needed a bit more R&D before being rolled out." ~ ChampionshipMission
"Came here to say this. Have you ever seen a child try to make a spaceship or a suit of armor out of cardboard, but they don't have enough cardboard and none of the pieces really fit together anyway, so they end up lashing it together with dozens of strips of tape at every possible angle until it just barely holds together? That's knees. That's how your knees are made." ~ DerCatzefragger
Tiny Humans
"Having sharpened rocks that slowly push their way through the sensitive gums of tiny humans who are too small to understand or explain the reason for their incessant crying.

"Edit: All this fibre talk, I get it. I now understand more about the importance of fibre. But that kinda adds to what I'm saying. Imagine not needing a summoning ritual. Like deciding when you do and don't drop the kids off at the pool. A human eject button." ~ J1ra1y4

Every single minute, the human body sheds more than 30,000 dead skin cells.
That's nearly 9 pounds per year.
The heart beats 100,000 times a day or 35 million times per year.
And the average person produces enough saliva to fill 2 swimming pools in their lifetime.
These facts only scratch the surface of everything the body has to offer.
Reddit user Zenssei asked the question:
"What is a fact about the human body that not many people know about?"
Of course, many find the brain especially fascinating. That little jelly orb is just about the primary reason human civilization is what it is.
Still Kicking
"Your brain continues to try to revive the body long after the heart has stopped. In some cases 30 hours later there has been found brain activity trying to make repairs to bring the body back."
"This is used to indicate time of death in murder victims."

"...the colors you see before you fall asleep are a common mild occurrence, there are several classes of these hallucinations, closed-eye visuals, which are caused by leaving your eyes closed for a long time, hypnagogia, which is caused by the onset of sleep, prisoners cinema, which is caused by looking into a dark place for a long time, ganzfeld effect, which is caused by blocking out all external stimuli, and Charles bonnet syndrome, caused by sight loss."

"Your stomach is surrounded by more brain cells (half a billion neurons) than the brain of a cat contains in total."
"It's your enteric nervous system. It controls digestion, operates autonomously, has its own memory, can handle its own reflexes, it has its own senses even."
"It's thought to have come about because of the blood-brain barrier and the main brain being locked away in the skull, a spinal column and nerves away from the critical action of nutrition."
-- Hattix
Other people were amazed by the human body's tendency to adapt when it needs.
Like Dust Settling
"When doing surgery were the doctors have to take out some organs, when placing them back, they dont have to be put back In the exact position there meant to be..."
"...your body kind of just, moves the organs into the correct position after the surgery"
-- IamaJarJar
How You Need To Be
"People who live in 'extreme' conditions for generations adapt in extreme ways. For example people that live in high elevations often have larger lungs and different blood makeup."
"Or my favorite is the Bajau people that live on the water and spend a lot of their time diving, their spleens have become 50% larger in order to store more blood."
Saving Insurance Costs
"Our bodies have the ability to perform there own bypass procedures. My grandfather went in for a scan and it showed a 100% blockage in one of his major arteries."
"The image also showed a new portion of the artery starting .25" before the blockage and then rejoining the artery .25" after the blockage completely bypassing the obstructed portion. He had never had surgery before this discovery."
-- KlaubDestauba
And finally, some spoke about lungs and the breath. It's one of the few bodily functions we can do both involuntarily and voluntarily.
There's plenty to talk about there.
No Need to Grow
"When you get conditioned to physical activity, your circulatory system adapts -- more blood, more vessels, more blood cells. But your lungs really don't."
"This is because no matter how much blood your heart is able to deliver to your lungs, the lungs still have no problem oxygenating it. This is why your oxygen saturation doesn't drop during exercise (unless you have a heart defect.)"
-- grenudist
Not What We'd Expect
"The sensation of suffocating isn't caused by the thing that actually kills you. You'll die from a lack of oxygen, but the feeling of suffocation is the result of being unable to exhale carbon dioxide."
"So if you started breathing in pure nitrogen while being able to exhale normally, you would pass out and die without ever feeling like you were suffocating. This also explains why some languages call nitrogen something like 'suffocation gas'."
-- Wurdan
Gimme Some of That Liquid Air Please
"In theory humans could breathe a liquid if it was super saturated with oxygen. It wouldn't be easy because the density of liquid being so much higher than air so after 15 mins or so you would be too fatigued to continue breathing."
"The hardest part is getting all the liquid out of the lungs so the person doesn't get pneumonia"
-- Crackracket
Head Hurts
"Migraine pain can lessen from vomiting. Vomiting can cause dehydration. Dehydration can cause migraines.The human body is funny. Migraines are the worst. It's like your brain is asking you to troubleshoot your body like tech. Sodium levels low? Magnesium maybe? Forget to eat? Blood pressure off? Exhausted? Stressed? Who knows..."
"Try a hot shower or an ice pack, chocolate, more caffeine, less caffeine, a triptan maybe, some almonds, put some pressure on your eyes, get out of the sun, get some sleep. If all else fails there's the old migraine cocktail at the doctor's office a shot in the neck, a shot in the butt, and an anti-nausea med under the tongue."
-- Acrobatic_Classic_13
8%
"The human genome is about 8% virus DNA. Over millions of years, various sequences of virus genes have gotten stuck in our DNA and copied faithfully ever since. Most of them are now nonfunctional, but at least a few of them seem to still work and actually code for useful proteins. This suggests that viruses might occasionally serve as a helpful source of mutation in the evolutionary process."

"Some people have inner monologue. Some don’t."
OF_AmericasGoddess
"According to my teenage son, people without internal monologues 'think in pictures or scenes, but not actual words.' He doesn't have an internal monologue. I do, and mine won't shut up. It's like a news ticker of my to-do list and my worries and conversations I need to have."

Eyes Turning
"If you squirt cold water into someone's ear with a syringe, their eyes will automatically turn to the side that you squirted the water. If you use warm water, their eyes will automatically turn to the other side."

Brain Waves
"Your brain continues to try to revive the body long after the heart has stopped. In some cases 30 hours later there has been found brain activity trying to make repairs to bring the body back. This is used to indicate time of death in murder victims."

Blind Spots
"Each one of your eyes has a blind spot where the optic nerve exit your eye into your brain. You can't see it because your brain tricks you not to see, it covers the spot with some made up image of what it thinks fits better with the rest of it. You can test and (un)see it for yourself here."

Vitamin C
"Humans are one of a few species of mammal that oddly don't produce their own vitamin C due to lack of a certain enzyme. Other mammalian species who exhibit this mutation are those contained in the main primate suborder Haplorhinni (monkeys, apes, tarsiers), as well as bats, capybaras, and guinea pigs. All other mammals produce vitamin C in the liver."

Palettes
"Apparently about 20% of people have a bony ridge on the roof of their mouth. Most people's palettes are smooth with a very slight ridge. The 20% like me have an exaggerated and more pronounced ridge. Apparently it's most common in women and Asian folk, and I'm neither so that's neat. I always thought it was totally normal."

Typed
"Positive blood type women can have positive and negative blood type babies without issue. Negative blood type women require a shot with antibodies to prevent the mothers immune system from attacking the fetus if it is a positive blood type."

"This was how my mother lost her son, Muhammad, late in her pregnancy. The bad joke of a government in the country my parents came from (Iraq) was notoriously unreliable at keeping records, and as such my mother’s blood type was mislabeled. It’s been 33 years and she still says she thinks about him every single day."

Broken Bones
"Babies can break their collarbone during delivery. It happens quite often, but heals quickly. My teacher told me that (if it happened to you ofc) you may feel a slightly higher spot on your collarbone, called the callus where the fracture grew back together."

Perhaps now is a good time to take a few minutes and think about all that's going on inside our bodies.
But don't think too hard though, it gets pretty weird.
