10 Things You Didn't Know About The Human Body


he human body performs thousands of functions every single day, from replacing your taste buds without you even knowing it to changing the pace of your heartbeat to mimic the music you’re listening to. The human body is an amazing, thriving powerhouse that’s equal parts sweaty, disgusting, nasty and beautiful. There are a bunch of strange and fascinating things you probably never knew about the human body. Even though these functions are essential and important to life, we were still shocked to find out just how much work goes into making our bodies function.

Our bodies are composed of extremely high levels of iron. Iron is an important component of hemoglobin that carries oxygen from our lungs and transports it throughout the entire body. If you were to take all of the iron out of our bodies, it would be enough to make a metal nail that’s three inches long. Pretty amazing, right?

Even our mouths go through some pretty amazing functions to keep everything in working order. The home to the jaw, the tongue and our teeth; the insides of our mouths are constantly producing saliva. In fact, on average, our mouths produce over 25,000 quarts of saliva throughout our entire lives. Saliva, which is made mostly of water, helps to protect our mouths from germs, it aids in digestions and it helps to keep our teeth nice and strong. During our lifetime, our mouths will produce more than enough saliva to fill two up swimming pools. Care to go for a dip?

If we move a little further up on the body, we’ll reach the eyes. If you’ve ever felt a twitch in your eye, it could be more than just your reflexes going wild. I could actually be a mite. Yes, that’s right, a mite! About half of the world’s population suffers from eyelash mites, but only 95% of those affected are bothered by these little critters. Eyelash mites are so tiny. They’re only a third of a millimeter in length. These creatures are able to survive by munching on your skin cells and the oils excreted by your eyes.

Going further down the body and past the midsection, you will find the navel. Our belly buttons are a thriving and flourishing environment of their own, believe it or not. This body part contains the same bacterial ecosystem that is found in most rainforests. The average navel is the home to 65 different species of bacteria, including the Micrococcus. The Micrococcus species thrives around the surface of your navel, and if you’re wondering how you can get rid of them, you’re out of luck. This species is able to survive through long periods of starvation and extreme droughts, so your dry flesh at the opening of your belly button is the perfect home for them.
