There are many ways we could look at the human body. "On an evolutionary scale, sometimes we are similar to animals, and sometimes we're not," general practitioner, medical researcher, and founder of PrimeHealth Clinical Research, Iris Gorfinkel, M.D., told Bored Panda. "We're symmetric, [our] basic body structure is similar; we have what's called homologous bone structure. In other words, you can find exact similarities between humans and other animals and how our bones are put together."

"Even our muscles and heart and vascular systems are similar. Our lungs are often similar too. [As well as] the fact that there's a long tube from the moment food enters our mouth to the point at which it goes out of our rectum," Gorfinkel explained. "Their breathing is similar to ours neurologically. Urologically (how urine is formed), we're also quite similar. In all of these aspects, we are very similar to animals."

“What Is A Fact About The Human Body That Not Many People Know About?” (50 Answers) 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.

“What Is A Fact About The Human Body That Not Many People Know About?” (50 Answers) You hate the sound of your recorded voice because it's missing the low frequency you're used to hearing.

When you talk, you hear your voice as it goes to the air and back to you ear. It also goes through your skull to your ear, and this bone conduction mechanism transmits the low frequencies better than air does.

Your recorded voice only has the air transmitted sound. That causes the dissonance between what you think your voice sounds like, and what it really does. It's also why your voice will (almost) always be higher pitch than you think.

But if we continue to measure ourselves against animals, we inevitably start noticing differences. "Animals communicate across miles of land through subsonic sound, that's true. But human beings, on the other hand, have very complex language systems," Gorfinkel said. "We have introspection—that's another critical difference, [as well as] our creativity and emotions, like joy and sorrow and grief—although grief has been described in some animals, including elephants, wolves, and sea lions. But the biggest difference that makes us humans a complete and utter separate category within the animal kingdom, is our ability to have an imagination, to use language in such a complex way, and to hold fictions in our mind."

The comparison that Gorfinkel thought of on the spot illustrates her point on a meta-level. "Let's just say the lion is the guardian spirit of our tribe. He still could never convince a monkey to give him a banana by promising the little guy, say, an unlimited supply of bananas in monkey heaven. So our ability to create and believe in collected fiction, that's what makes human beings really different."

Some parts of our body, however, remain unknown even to science. Take the human brain for example. It has approximately 86 billion neurons, woven together by an estimated 100 trillion connections, or synapses. So untangling such a delicate network is a daunting task—we don't know the details of how those cells work, let alone how they come together to make up our sensory systems, our behavior, our consciousness.

"You would think it would be easy [to study the brain], it weighs only three pounds, and three-quarters of it is water and 60% of it is fatty tissue. And you'd also think it's easy because the brain can't feel pain. You know, surgery could be done on it, allowing for easy experimentation, as inhumane as it sounds. But there are several things that make it extremely difficult," Gorfinkel said.

"[Our billions of neurons], connected by trillions upon trillions of synapses in a barrel, is a veritable neuronal forest, and the information is moving at all different speeds, some up to, I think, 250 miles an hour. So even with things like functional MRI [we don't get close to] the nitty-gritty of understanding the very fine neuronal connections that are happening, that really define memory, that define all the complexity that I was just describing: language, reason, creativity, and emotions."

Christof Koch, Ph.D., Chief Scientist and President of the Allen Institute for Brain Science, and his colleagues study the brain on a large scale. But the more they look at many or most cells in the brain rather than just a few, the more they realize that even the parts of neuroscience they thought the field had nailed down are more complicated than anyone had realized.

"There may not be any simple path to understanding complex systems shaped by natural selection,” Koch thinks. "Evolution doesn't care about elegance. The brain doesn't care if you understand it."

But that doesn't mean we should stop learning. On the contrary. There's plenty we can do as individuals and as a society to get a better understanding of ourselves and in turn, those around us. "Emotional education is sadly lacking in schools," Gorfinkel said. "We teach all kinds of useless things. And I hate to say it... They're not useless, but they're not as relative to us as understanding our emotional selves."

The doctor said there is precious little time devoted in schools to understanding emotions, such as anger, humiliation, shame, guilt, and what to do when we face them. Instead, they're often presented as something negative we need to control, as opposed to being contextualized. These emotions can actually help us, show us the path towards what needs to be done next. "They shine a light on how we need to manage our lives better," Gorfinkel explained.

"That is something that has long bothered me. Emotional education is, for the most part, not focused on; we focus on physical education, we focus on [general] education [like] mathematics, physics, chemistry, biochemistry, whatever it is, but a lot of the time, the most critical part that will determine our happiness, and our productivity is completely overlooked."

Because of that, we have to do it ourselves. "Just make the most of picking the low lying fruit," Gorfinkel said. "I'm talking about [things like] sleep or finding the right amount of stress in your life—stress is an interesting thing. Too little stress is actually bad for a person, there's a sweet spot when it comes to stress. And it's kind of a bell curve, right? That if you have too little, there's not enough stimulation. And a person does not approach self-actualization. Even though stress is roundly considered a negative thing, in fact, a little bit, just the right amount is a positive thing. Of course, it can turn into a very negative thing if there's too much. But finding the sweet spot of stress is probably the best tip that I could give."

Your body will reduce your muscle strength to protect your spine.

Stand on flat ground, hold your arms out in a t-pose, and have a friend push down on your hand while you try to hold it in place. That's your control, how strong you actually are.

Now, remove 1 shoe (or put a book under 1 foot) and repeat with your hips askew so your spine isn't straight. An inch is all it takes.

Anyhow, another proof of common ancestry of the primates as we all have that same mutation in our genes.

Well that's not strictly true - because of the shape of the lower intestine and colon, they never really empty fully. It's very rarely 20lbs worth (you would be extremely ill if that was the case) but there's certainly areas that don't fully clean and bad bacteria can build up there. These drinks and pills work by irritating the gut so badly that everything gets removed, including good bacteria so they are not a healthy option, but they do technically do what they claim.

The whole gut tube is not a static rigid pipe! It has rhythmic contractions called peristalsis that ensures ALL the content is circulated. It doesn't need to fully empty, but all content is passing through. If ANY content stagnates you get severe emergency diseases that warrant surgery, not a miracle colon cleanse.

HOWEVER.... the walls of your intestines CAN be coated with "toxic poop" (it only takes several ounces) which can increase your risk of colorectal cancer, prevent absorption of beneficial nutrients, harm the helpful bacterial fauna in your stomach, and give you cravings for otherwise unhealthy food. The BEST thing to do is to eat a lot of fiber, as high-fiber stools act as wet sponges to gradually wash away the toxic poop. But oddly, an occasional bout of diarrhea will rinse it away, as anyone who has been told to drink citrate before a colonoscopy will know. (The idea is to rinse away the poop so the doctors can see the colon wall.)

People with low heart rates have been known to pass out on the toilet because their bodies can't handle the shift.

It's also why EMTs will absolutely not let you use the bathroom before getting on the ambulance. Especially if the bathroom is a standard 5'x8'.

“What Is A Fact About The Human Body That Not Many People Know About?” (50 Answers) 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.)

“What Is A Fact About The Human Body That Not Many People Know About?” (50 Answers) There's a "right" and a "wrong" way to swallow and the first swallow pattern you learn isn't the right one! Babies swallow by pushing their whole tongue forward (since it's better for nursing). However, as you transition to solid foods, you are supposed to change to a swallow where you put the tip of your tongue on the roof of your mouth and roll the food back. Not everyone does, and those that don't are more likely to choke, eat too fast, develop dental problems, and some develop a lisp or distorted sounds as they learn to talk!

The hardest part is getting all the liquid out of the lungs so the person doesn't get pneumonia

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.

The shoulder blade is a more complicated joint than you'd think. While the hip is a ball and socket that just rotates, the shoulder can fold forward. If you sit with your back against against the chair, hold your hand on your collarbone. Then try moving your shoulder forward.

Virutally all are deceptive/misleading due to phrasing. If the one about muscles were true, for example, then we'd be strong enough when our brains decided we should be ----- and, in the example given, lifting a car off a child would snap our femurs. It doesn't. This is a physiological response due to *adrenaline*, and if you think you don't hurt after, you're mistaken. Situs inversus is caused by a rare combination of genetic factors, and most with SI do NOT have the ciliary dyskinesia (PCD for short). And you get PCD without having SI. And so on. So, please, do not take these as "fact". (signed, have my MD)

While I agree with those who already posted that many of these are misleading because of how poorly worded they are, or plain factually wrong, I hope for our sake the general public hasn't come to expect learning medicine/anatomy/physiology on an entertainment site that holds no fact checking responsibilities. I hope this incites curiosity to learn more about the human body! Please look up reputable authors that have books accessible to the wide public. I recommend Oliver Sacks' books, a neurologist and writer for fascinating trips into the human nervous system!
