Your skin is home to billions of creatures
At first glance, our bodies may seem like one of the world’s many amazing scientific marvels – from atoms to outer space! But closer inspection reveals their true magnificence. From eye color and hair growth patterns to genetic inheritance – there’s so much we have yet to learn about ourselves and each other! Continue reading this fun and fascinating read and uncover even more mind-boggling facts!
Our skin is the largest organ in our bodies and home to billions of microbes that live on it – from microscopic bugs and mites, lice, and parasites to lice and other parasites – living there. While some organisms may provide benefits such as breaking down fat, producing vitamin D and detoxifying our systems, others could potentially pose harm if our immune systems become compromised or they reproduce uncontrollably.
Humans possess over 2.5 million sweat glands and shed between 30-40 skin cells every minute, thanks to these sweat glands’ specialization in producing salts, glucose, vitamins, and amino acids to fuel our bodies – not forgetting creating a watery soup of nutrients to keep skin, hair and eyes healthy!
Scientists have discovered fossilized examples of early skin on birds, mammals and reptiles which indicate its significance during the transition from aquatic environments to land environments. Scientists hypothesize that early skin was essential in protecting these species’ vital organs while they adjusted to new terrestrial habitats.
Human adults possess 206 bones that comprise their skeleton, while infants are born with approximately 300 but as they develop some may fuse together and some die off altogether. There are 27 hands bones and 26 feet bones (106 total). Our skeleton is continuously being remodelled as new bone replaces old tissue.
Human bodies contain millions of nerve endings that allow us to feel touch, pressure and temperature. Our eyes can see in low light conditions while our ears hear even when we’re not speaking and our noses detect thousands of different smells.

Your eyes are the largest organ in your body
Your eyes capture all of the shapes, colors and movements around you and translate this data into something your brain can understand through a system of nerves and cells called retina (pronounced: RETI-nuh). Your retina consists of two components; first is your pupil which regulates how much light enters your eye while lens focuses light rays onto the back of your eyeball for three dimensional viewing as well as color vision. When both parts work properly you’ll have three-dimensional and color vision vision.
Your body is home to trillions of cells that work in harmony to keep you alive.
