“The human body is the best work of art.” ― Jess C. Scott
Like our own bodies, few things are as complex and interesting to us. Each one we have only one, and it’s supported by thousands of parts working in unison. Understanding the pieces that make us who we are and how they work together is interesting!
Here are 30 facts about the human body!
50. Who shed all over the carpet?
Humans shed about 600,000 particles of skin every hour. In fact, most of the dust underneath your bed is probably your own dead skin.
49. Baby bones.
A human baby has 99 more bones than an adult. A baby’s skeleton is mostly made up of cartilage. As a person grows up, most of this cartilage turns into bone in a process called ossification, and the ossification process results in the joining of certain bones. Consequently, new born babies have around 305 bones, while an adult has just 206 bones.
48. A few small pieces.
An adult human being is made of approximately 7,000,000,000,000,000,000,000,000,000 atoms. Obviously, this varies based on the size of the person and their body composition.
47. Pumping the distance.
There are 100,000 miles of blood vessels in an adult human body. The largest blood vessel is the aorta, which is just over an inch in diameter.
46. Our awesome noses.
Researchers estimate that the average human being can distinguish between 1 trillion different odors. This is much more acute than the human eye, which can distinguish about 10 million different colors.
45. Swimming in spit.
In a lifetime, an average person produces about 25,000 quarts of saliva, enough to fill two swimming pools. We also produce about a litre of mucus per day.
44. It lives in you.
Your body has enough iron in it to forge a 3-inches-long nail. You also have enough sulfur to kill all fleas on an average dog, enough carbon to make 900 pencils, enough potassium to fire a toy cannon, enough fat to make 7 bars of soap, enough phosphorous to make 2,200 match heads, and enough water to fill a ten-gallon tank.
43. Close your eyes.
We all have tiny mites living in our eyelashes. These little mites actually aren’t too choosey; they’ll live anywhere as long as they have access hair follicles. They’re found on other parts of the body and on a host of other mammals.
42. The strongest muscle.
Pound for pound, the strongest muscle in the human body is the masseter (jaw muscle). It can clamp your chompers shut with 55 pounds of force on the incisors and 200 pounds of force on the molars.
41. Stinky humans.
Sweat itself is odorless. It’s the bacteria on the skin that mingles with it and produces body odor. Bacteria that are naturally present on our skin thrive in sweaty regions.
40. Growing strong.
Your ears and nose will never stop growing until the day you die. In fact, your earlobes will also elongate from gravity.
39. Don’t lick the gun.
Similar to fingerprints, everyone also has a unique tongue print. It may be some time before your local police station starts taking tongue prints, but research on the required 3-D imaging technology is already being developed and tested.
38. Strength if steel.
Ounce for ounce, human bones are stronger than steel. A cubic inch of bone can bear a load of 19,000 lbs.—roughly the weight of five pickup trucks.
37. Booze and blue.
People with blue eyes have a higher alcohol tolerance. Interestingly, they also have higher rates of alcohol abuse and dependency.
36. Better sight than your iPhone.
If the human eye was a digital camera it would have 576 megapixels. Currently, the most expensive digital camera in the world has 200 megapixels.
35. Carrying some friends with you…
All of the bacteria in our body collectively weighs about 4 pounds. That’s enough to fill a big soup can. In fact, there are more bacteria in your mouth than there are people in the world.
34. Move to the music!
In some cardiovascular units, slow and quiet music is used to relax the patients and lower their blood pressure and heart rate.
33. Brain power.
Your brain accounts for only 2% of your body weight, yet it uses 20% of the total oxygen and blood in your body.
32. Deoxyribonucleic acid (DNA).
If uncoiled, the DNA in all of your body’s cells would stretch 10 billion miles, which is long enough to reach from here to Pluto and back.
31. Eaten from the inside…
Within three days of death, the enzymes that once digested your dinner begin to eat you. Ruptured cells will become food for the bacteria in your gut, which will release enough noxious gas to bloat your body and force your eyes to bulge outward.
30. Supercomputer storage.
In a lifetime, your brain’s long-term memory can hold up to 1 quadrillion (1 million billion) bits of information.
29. The perilous journey of a hot dog.
The gastrointestinal tract is a 30-foot tube that runs from your mouth to your anus. There’s a few moving parts, but a long story short is that food comes in and poop goes out.
28. Barrels of blood.
Your heart will pump about 1.5 million barrels of blood during your lifetime. That’s enough to fill 200 train tank cars.
27. You can’t stop the beat.
As long as it has an oxygen supply, your heart can keep beating even if it’s separated from the body because it has its own electrical impulse.
26. Brain age.
Your brain keeps developing until your late 40s.
25. Sweet cilia.
Our lungs and nasal passages have exquisitely tiny hairs called cilia that can “taste” bitter flavors. They also serve to remove dust and foreign particles from the respiratory tract.
24. You feel me?
Human fingers can feel objects as small as 13 nanometers. This means that if your finger was the size of the Earth, you would feel the difference between houses and cars.
23. A heck of a fever.
The highest recorded body temperature in a human being was a fever of 115.7°F. A fever over 107.5°F is enough to damage the brain and, if untreated, cause death.
22. Touch your heart.
The human heart is not on the left-hand side of the body. It’s in middle of your chest, in between your right and left lung. It is, however, tilted very slightly to the left.
21. Brain genes.
Half of your genes describe the complex design of your brain, with the other half describing the organization of the other 98% of your body.
20. Cell replacement.
Your taste buds are replaced every 10 days. Conversely, the average age of a human fat cell is 10 years.
