10 Surprising Facts About the Human Body
Facts About Your Eyes
Did you know that your eyes can distinguish about 10 million different colors? That’s why you’re able to enjoy the colorful world around you. Furthermore, your eyes blink 20 times per minute without you even realizing it. Blinking is your body’s natural way of preventing your eyes from drying out and staying healthy.
Facts About Your Skin
Your skin is the largest organ of your body, and it weights around 6 pounds. While you go through life, you also lose about 40 pounds of skin throughout your lifetime. Moreover, your skin can heal itself from small cuts or injuries, which means it can actually regenerate and renew itself.
Facts About Your Skeleton
Your skeleton is made up of over 200 bones, and these bones are directly connected to muscles and ligaments within your body. Surprisingly enough, the teardrops you sometimes see in your eyes are bone-related; they’re not from crying.
Facts About Your Hair
Your hair is actually made up of the same substance as your nails, keratin, and that’s why both need to be trimmed whenever they get too long. Additionally, the hair on your head grows about 0.5 inches per month, so that’s a half-foot of hair every year!
Facts About Your Mouth
It’s impossible to tickle yourself, including on the roof of your mouth. So, the next time you’re trying to do that, give up the task respectfully. Furthermore, the acid created from your saliva can start digesting your meal even before it reaches your digestive system.
Facts About Your Brain
Your brain keeps developing and changing throughout your lifetime, and it includes around 100 billion neurons. Amazingly, this small part of your cranium uses up 20% of your body’s energy. Research also shows that your brain activity doesn’t completely stop even while sleeping.
Facts About Your Heart
Your heart pumps blood to every part of your body twenty-four hours a day, seven days a week entirely. Believe it or not, laughter is actually great for your heart since it triggers the very same physiological reactions as a workout. On the other hand, not getting enough sleep can contribute to heart diseases.
Facts About Your Lungs
You probably think your nose and mouth control your breathing, but it’s actually the power of your diaphragm that does that. That’s the reason why people struggling to breathe only breathe into and out of their abdomens. Furthermore, your lungs take up around 5% of your total body weight.
Facts About Your Digestive System
Your digestive system starts at your mouth and works its way through various other organs until you excrete. It’s pretty incredible to learn that the food you eat will take at least 24-72 hours to pass to your anus once it consumed.
Facts About Your Movements
Your movements are fueled by the electromagnetic impulses sent through your cells rather than some unknown force. Additionally, it takes approximately 200 muscles in perfect coordination to take a single step.
