Hey YouTube, Jim here!
Welcome to Top10Archive!
We’re with it 24 hours a day, 7 days a week, but there are still aspects of it that continue
to perplex us.
We are, of course, talking about the human body.
On our quest to understand these impressive vessels even better, we’ve done some inner
digging and discovered these top ten amazing facts you probably didn’t know about your
own body.

The Appendix Has A Use For many years we were removing appendixes
all willy nilly, exclaiming “You don’t need that, it doesn’t do anything!”
Weeeeeell, turns out that’s not entirely true.
The once-believed-useless organ actually serves as storage for back-up “good bacteria”
typically found in our gut.
When an infection removes this bacteria, it’s suggested that the appendix repopulates the
beneficial microbes, or innate lymphoid cells, with its reserved supply, which then helps
fight off future infections.
Now, to see about getting a replacement…
Any of you still have your appendix?
9.
Belly Button Bacteria Ah, the belly button.
It looks cute and harmless, but don’t let it fool you.
Our navels are actually teeming with bacteria.
And by teeming, we mean present in numbers in the thousands.
During a study performed by researchers in North Carolina (who apparently were doing
some navel gazing), 60 belly buttons were swabbed and over 2,300 different species of
bacteria were found.
Even more interesting is that each sampling showed a different composition of bacteria
for each belly button.
(That should make naval gazing much more interesting now!)
8.
Cardiovascular Rhythm Huh, well I’ll be danged.
Deee-Lite was right.
Groove IS in the heart!
Music can have plenty of positive effects on the human body and mind, but we bet you
never thought regulating your heart would be one of them.
Luciano Bernardi of the University of Pavia in Italy suggests that the cardiovascular
system alters when music is played based on research that determined that crescendos led
to an increase in blood pressure and heart rate while decrescendos had an opposite effect.
When tested with something more operatic, the cardiovascular system was found to synchronize
to the tunes (but also led to severe headaches and brain damage … just kidding about that
last part).
7.
Atoms of the Body If you were to break down the human body to
a molecular level, you’d have one ugly mess on your hands, but within that molecular goo,
you’d be able to pinpoint an exorbitant number of atoms.
That is, if you had the time to count over 7 billion billion billion atoms.
If you can’t visualize that number, it’s a 7 with 27 zeroes after it.
Or, for a more technical term, it’s a lot.
Despite being chock full of atoms, we’re still filled with a lot of empty space, giving
credence to that feeling of emptiness that pesters you.
6.
The Strongest Muscle You probably think those killer biceps you’ve
been working on are the strongest muscle in your body, right?
If you’re talking strength based on weight, it’s actually the masseter, or the muscle
running from the temporal bone to your lower jaw that’s responsible for chewing.
While nothing compared to the bite force of the West Nile Crocodile, the masseter exerts
a force of 200 lbs per square inch (90 kg) on the molars.
Other strong muscles you may often overlook include those of the uterus, your glutes,
and your tongue.
5.
Half of the Elements You know that dreaded Periodic Table that
you’re being forced to learn in Chemistry but don’t want to be bothered with?
Yeah, you may want to pay attention to it because about half of it can be found within
your body!
Yes, we’re more than just meaty flesh sacks that bleed.
If you were to break down the human body into its elemental composition, you’d find about
65% is made up of oxygen, 18% carbon, 9.5% hydrogen, 3.2% nitrogen, and a trace amount
of elements like sodium, sulfur, and chlorine. 4.
The Strong Little Finger Though it’s smaller than the rest and may
look pretty useless, your pinky finger is more important than you may figure.
You can continue accessorizing it, but just show a little respect because, once it’s
gone, you could easily lose up to half of your hand strength.
Though fragile, the pinky requires nine different muscles in your fingers to contract.
Despite its muscle composition, the pinky also has the smallest range of motion.
Really!
We pinky swear!

The 500 Functions of the Liver Now before you take another swig from that
bottle of Grey Goose you’ve been nursing, maybe you should know what your liver does
before you continue down your path of murdering it.
In total, the liver has approximately 500 different functions, including assimilating
and storing fat-soluble vitamins, providing blood clotting factors, removing damaged red
blood cells, and filters the blood to remove harmful chemicals and bacteria.
Though we can’t walk through every function, here’s a list of some of the more important
ones (feel free to memorize these …. there will be a test in the comments section)

Life After Death Oh, no, we’re sorry!
We didn’t stumble upon some answer to one of the universe’s greatest questions.
We are here, however, to tell you that, after your death, your body turns into a veritable
ecosystem brimming with bacteria.
Specifically within the gut, the bacteria needs something to feed on, so it starts to
eat away at the intestines and surrounding tissue.
Within 20 hours, it travels to the liver and, just after two days, spreads to the rest of
the organs.
Before long, your tissue starts to break down and putrefaction of your body begins.

Spark of Genius Why are we worrying about natural-source energy
and sustainable, renewable energy when we can all pull an “Uncle Fester” and power
light bulbs with the energy from our brains?
Alright, so maybe it doesn’t work quite like that, but it is true that the human brain
contains over 100 billion neurons that individually generate a small amount of electricity during
everyday processes.
If combined into one power source, the bunching of neurons could easily power a low-wattage
light bulb.
