Our bodies are incredibly intricate machines, so naturally, maintaining and troubleshooting them when something goes wrong can be quite difficult. So it's important that we are at least somewhat familiar with the "user manual." Otherwise, we risk handing our health & wellness to guesswork and hearsay.
A recent Reddit post asked everyone on the platform to list the facts about our anatomy that many grown-ups still don't understand, and thousands jumped in to share the ignorance they've encountered. From growth to metabolism and reproduction, it looks like plenty of folks need to revisit high school biology.

Bra sizing, it doesn't help that most major manufacturers and sellers of bras also don't know how it works.

While an erection or lack thereof could signify a physical attraction, it should not be used as an indicator of it one way or the other. Your mental state is the biggest factor with what happens down there.

To put things into perspective, consider this: a survey commissioned by USANA and conducted by OnePoll found that two-thirds of Americans could not identify the commonly assumed average body temperature as 98.6°F.
Furthermore, 35% of Americans did not know their own blood type, and nearly three in 10 (29%) could not tell the difference between a liver and a kidney.
A third of respondents also did not know that the human body has two kidneys—with one in five believing the body has three or more.

I’ve been surprised at the lack of knowledge men have about the v****a and reproductive system.
Once a guy said he doesn’t have period s*x because he doesn’t want an std. I’m like what?! So I explained how that doesn’t give you an std.
And then another time a guy mentioned how he didn’t know why women didn’t just take the time to squeeze and push out all the period blood all at once and save the hassle of it coming out for days (?!).
Then another time where I had to explain that a cramp wasn’t just the blood being clogged at the end, it’s the uterus squeezing to help itself shed. Shed what?, he says.
I don’t understand. These people had the same s*x ed I did, how did this happen?

Awkward sentence to say but, qu*efing. Many people don't realize that when you pull out and swap positions air WILL rush in, and then be forced out when you put it back in.
And girls, we don't care at all. So stop being embarrassed about it.

The Clitoris isn't just a tiny bean, it actually has 5 arms; one goes to the Clitoris and the remaining 4 go to each of the Labia Minora and Majora.
So Guys; don't just focus on the Clit!
Also Vulvas aren't identical. Only a small proportion of women have Innies. Most women have Labia Minora which protude. Labia Minora can be smooth or frilled, different lengths, shapes & colour to the surrounding skin. Its normal but many women have been taught to think of their genitals as ugly and shameful and it needs to stop.

Nearly a third of the survey's respondents thought the lungs played a part in the body's detox system, while roughly one in five mistakenly named the heart (21%) or bones (19%).
At the same time, four in five respondents consider themselves knowledgeable about the human body.
Fortunately, people do want to learn more. Forty-three percent of those surveyed said they would like to expand their knowledge of mental health, while 38% want to look into cardiology, and 32% want further education on reproductive health.

If you stick ur hand in ur crack after a shower and it does not come out smelling like the rest of your body, you need to get back in the shower because you are not done yet. Scrub IN the crack. You should know what your sphincter feels like.

People who want their pregnancies can still end up having to terminate them if there's a medical emergency. Just earlier today, I saw a post on FB about women who have died in that situation because of abortion bans. Of course, some unempathetic waste of space had to comment about how they could have just not had s*x.

What’s alarming is a lot of women don’t know they will have significantly different symptoms to what men experience during a heart attack. This is due to medical science using male anatomy even into the 2020s to diagnose female health issues.

Shocked how many guys think women can “hold” their period, like it’s pee. Not only is this not the case, exerting your core muscles or bending/moving around a lot pushes more blood out, which sometimes feels a little alarming.

The whole IVF/embryo development process. It was crazy concerning to me how many people in my life don’t know the insanely basic stages of embryo development (edit: regardless if it’s in a testing tube or the body!) that should have been taught in middle school science. Not all fertilized eggs even result in a zygote and not all zygotes result in an embryo that will make it to blastocyst. And not all healthy embryos will implant.
I have a family member who is insanely against IVF even though that’s how we had to have my daughter. She posts the most insane s**t how “IVF kills babies”. She is a 40 year old nurse. Just amazes me how far she got in life being so intentionally stupid.

You are not your body.
You are a brain, piloting a calcium mech frame, wrapped in meat.

The breathing hole being next to the feeding hole is definitely the most NSFW element of the human body. If you were building a living organism from scratch that would be a major code violation.

I've worked as an OnlyFans chatter for almost two years and have spoken with several thousand people. An alarming number of men think squirting equals orgasm for women, 'No squirt, she didn't c*m,' and 'If she squirted, she c*me.' Neither of those things is true.

If the voltage is high enough, as a human you do not have to actually touch it to get shocked. It will jump out and hit you if you get to close.

Bruh. The fact that women dont pee out of their v****a.
I deada*s had an ex who thought I was an idiot and completely wrong for telling her that she has 3 holes down under. She was convinced that it was a*s n vag. Unreal.

S*men takes 64–74 days to fully develop.
Just found out the entire process from creation to maturity takes about 2.5 months. It happens in two phases - 50–60 days of development in the testicles, then 10–14 days in the epididymis where they learn to swim.
Also wild: if they’re never released, your body just breaks them down and reabsorbs them.
