"Your Brain Blocks Out The Noise Of Your Organs Moving": 18 Horrifying Human Body Facts That Are Going Viral On TikTok Right Now

In a "bored" moment, TikToker @emmakeeleykawesha recently asked a question I bet they now regret: What's the grossest fact about the human body? What people shared is stomach-turning, so read at your own risk...

NOTE: I did my best due diligence to verify these facts through online research, but I cannot verify with 100% certainty that every single one is true.

1.Let's start with the chin muscle. We all have one, but do you know what it looks like?

It is called your mentalis muscle, and I blurred it to spare your eyes. If you insist on knowing, you can see what it looks like here.

2.Pregnant people can develop allergies to their own skin or have skin issues that look like allergic reactions. While it is rare, these allergens can cause your skin to peel off.

3.Interestingly enough, intestines can move during surgery, but their movement is typically reduced by anesthesia.

4.A teratoma is a tumor that contains tissue from multiple body parts — it can grow hair, teeth, or even eyes.

When teratomas were first discovered, they resembled malformed fetuses. I highly suggest you don't look at it, but if you must, here it is.

5.And a congenital orbital teratoma is found in the eye sockets of babies. This one is also extremely disturbing, so if you want to see it and learn more, you can do so here.

6.When you blush, your stomach lining can also take on a reddish hue because of the heightened blood flow that occurs when your body releases adrenaline in reaction to feelings of embarrassment or stress.

7.When someone is nearing death, they may release a distinct scent known as the "smell of death," which is associated with the breakdown of tissues and organs.

8.This one is NOT true, but the newborn baby scent may be a combination of amniotic fluid, vernix caseosa, sebaceous glands, and sweat glands.

9.Hypochondria is said to cause changes in gray matter volume in certain brain regions. This can create heightened sensitivity to bodily sensations being interpreted as serious illnesses.

10.Lack of sleep can lead the brain to deteriorate where it can essentially "consume" its own connections, like synapses and waste, in a process known as autophagy.

11.Your eyes have an immune system called ocular immune privilege, which protects vision and minimizes inflammation. It is different from the rest of the body's immune system.

12.While the death rattle before dying IS real, it is not quiet. It is said to be a crackling, wet sound you may hear with each breath when a person is not strong enough to clear the secretions from their throat.

13.Cerebrospinal fluid (CSF) acts as a waste removal system — or rinse cycle — in your brain while you sleep.

14.I'm not sure about this one, but here is an article claiming that your lungs can smell.

15.This is known as a postmortem fetal extrusion or a coffin birth. Fetuses can also be born when the mother is brain-dead.

16.Post-mortem movement is real. This happens when ligaments are drying out, and muscles start to contract.

17.Your brain does, indeed, know where all your organs are.

18.And, apparently, your brain may tune out the sounds your organs are actually making.
