Human Body Is Weird… (14 GIFS)

Babies have more bones than adults

 

The average adult has roughly 206 bones in their body while a child has about 300. The difference is caused due to cartilage and bones that have not fused together yet.

 

Humans glow in the dark

 

The chemical reactions in the human body emit tiny amounts of light that scientists have been able to capture with ultra-sensitive cameras. Unfortunately, we cannot see it with the naked eye as it is a thousand times weaker than what we can detect.

 

Your appendix isn’t useless

 

The exact use of the appendix is still debated among scientists, but current thinking is that it may serve as a backup storage site for our “good” gut bacteria.

Goosebumps are your skin trying to keep warm

 

Due to having limited body hair, goosebumps don’t work as well as they do on squirrels or birds. Surprisingly though, goosebumps are the bodies way of trying to stay warm. There is a tiny muscle, the arrector pili, that contracts at each hair follicle to pull the hair upright.

 

You only breathe through one nostril at a time

 

While we typically only realize this when we have a cold, our body only allows us to breathe through one nostril at a time, even when healthy.

 

We have invisible stripes

 

The human body has a similar stripe pattern as Tigers, we just cant see them. Our stripes, called Blaschko lines, are formed as our cells are dividing and our body is growing in utero. The rows of cells look identical but certain rashes follow the lines, making them visible. They can also sometimes be seen under a powerful ultraviolet light.

 

Everyone’s pee stinks, even if you can’t personally smell it

 

Yep, we are talking about bodily fluids now. Strange enough, people who say that they don’t have fragrant pee also can’t detect the stink of other peoples urine. The current theory is that we all produce the odor but only some people can smell it as part of our bodies evolution.

 

Babies only blink once or twice a minute

 

The average adult blinks 10-15 times per minute while babies only blink once or twice. Scientists are unsure of why but believe it is because they tend to stare at things for longer stretches.

 

Your stomach is constantly digesting itself

 

The stomach contains so many enzymes and acids that it slowly digests itself. Luckily the body produces cells quickly enough to replace the cells that get destroyed every day. We end up with a new stomach lining about every three days.

Your DNA is 99.9% identical to a strangers

 

Genetically, all humans have about 99.9% of their DNA in common. All the differences between you and a stranger are within the remaining .1%. If that isn’t shocking enough, you share about 98.8% of your DNA with a chimp.

 

Your body produces enough saliva each year to fill a bathtub or two

 

The body makes .7 liters of saliva a day. That is roughly 68 gallons per year.

 

Gravity makes you shorter

 

When astronaut Scott Kelly returned from space, he was two inches taller than his twin. People are typically slightly taller in the morning than we are by the end of the day.

 

Teeth are not bones

 

Teeth have a coating called enamel (the hardest substance in the human body), are made of dentin underneath, and have a pulp full of nerves and blood vessels on the inside. Bones, by contrast, have fatty marrow and/or something called “spongy bone” on the inside, and the outside of the bone is coated in a membrane. Bone is full of collagen and blood vessels; the hard parts of teeth have neither.

Micajah,
Some idiot didn't get the science facts right, there is a DOMINANCE of one nostril, and it shifts every couple of hours to another one, but it sure is not 100% one nostril, in normal circumstances.

#5 Doesn't explain why raised hair follicles would help with warmth. It's because the erect hair (once upon a time fur) would trap air which is an effective insulator for the same reason fiberglass wool is used as insulation in the walls in some forms of construction (eg, Canada & USA).
