The human body is the structure of a human being. It is composed of many different types of cells that together create tissues and subsequently organ systems. They ensure homeostasis and the viability of the human body. It comprises a head, hair, neck, trunk (which includes the thorax and abdomen), arms and hands, legs and feet. As our body is a complex structure, whenever we face any issues related to our health, we prefer to consult a Physician first. However, in the below article “Surprising FACTS About Human Body” we will learn about 70 interesting facts about our body which we should be aware of.
70 Surprising FACTS About Human Body
1 – Our eyes blinks 20 times a minute.
2 – Our eyes and nose never stop growing.
3 – Once the oxygen supply is cut off, a human brain can survive up to three to six minutes.
4 – Throughout our life span, we go from having 300 bones to 206 bones.
5 – A human heart can beat outside the body as well.
6 – One-fourth of the bones in a human body are in the feet.

8 – Our mouth produces about one liter of saliva each day.
9 – Babies don’t shed tears until they’re at least one month old.
10 – Human teeth are just as strong as shark teeth.
11 – Scientists estimate that the nose can recognize a trillion different scents!
12 – The human tongue is the strongest muscle.
13 – Our body produces a glimmer of light, but unfortunately it’s invisible to the naked eye
14 – Our liver is the only organ that can completely regenerate itself. If someone donated his or her liver to someone else, their liver would grow back to its original size again in a few weeks.
15 – Blood is 6 times thicker than water.
16 – The longest bone is the thigh bone ( The Femur ).
17 – The stapes or stirrup present in the middle ear is the smallest bone.
18 – The hardest bone is the jawbone.
19 – Skin is the largest organ.
20 – An average person breathes 20,000 times a day.
21 – Yawning helps us to inhale more oxygen into our lungs. We usually yawn as our brain sends a message to our sensory system when it senses the shortage of oxygen.
22 – In a day, blood totally travels about the distance of 19,312 kilometres and our heart pumps around 1.5 million barrels of blood in our lifetime, which can fill 200 train fuel tank.
23 – The human heart beats 100,000 times per day and 30 million times a year.
24 – Cornea, the transparent front part of the eye is the only part with no blood supply and it gets oxygen directly from the air.
25 – The human ears can hear sound in the frequency of 2,000 to 60,000 hertz and can distinguish between hundreds of thousands of different sounds.
26 – The fingernails grow faster than toenails and the nail on the middle finger grows faster than the other fingernails.
27 – We cannot breathe and swallow at the same time. But the new-born babies can breathe and swallow both at the same time for up to their 7 to 8 months.
28 – About 99% of the total calcium content in the body is present in the teeth.
29 – Humans are 65% oxygen ( mostly in the form of water H2O )
30 – The human brain has two halves. The halves are called hemispheres! The left hemisphere controls the right side of your body and vice versa.
31 – A meal takes around 18-30 hours to pass through us.
32 – Identical twins have different fingerprints.
33 – We sweat about 500ml of liquid each day.
34 – Nails grow fastest in summer.
35 – The average person spends ⅓ of their life asleep! That’s 4 months out of every year.
36 – There are only three areas of skin that don’t grow hair. These are your lips, palms of hands and soles of feet!
37 – Sweat doesn’t smell bad. A stinky “body odour” is caused when the skin bacteria feed on sweat. Their waste products are what smell bad!
38 – The Brain is a very wrinkly organ! If we spread it out, our brain would be about the size of a pillowcase. By the time we are six years old, our brain is already 90 percent of the size it will be when we are an adult
39 – The liver has an amazing ability to grow back if part of it is removed due to injury, disease, or surgery. It will even grow to be just the right size for the body it’s in.
40 – Hair is the second fastest growing tissue in our body after the bone marrow.
41 – Onychophagia’ is the proper medical name given to the biting of nails.
42 – A newborn baby is found to have only 1 cup of blood in circulation (around 240 mL).
43 – Our blood vessels are super long (around 60,000 miles in length) and could cover the globe a little more than twice if laid out flat end to end.
44 – The hardest-working organ? Our heart.
45 – Teeth are considered part of the skeletal system, but are not counted as bones.
46 – Despite accounting for 2% of our body mass, the brain uses 20% of our oxygen and blood supply.
47 – The brain operates on the same amount of power as 10-watt light bulb. Our brain generates as much energy as a small light bulb even when you’re sleeping.
48 – The human brain cell can hold 5 times as much information as the Encyclopedia Britannica. Or any other encyclopedia for that matter. Scientists have yet to settle on a definitive amount, but the storage capacity of the brain in electronic terms is thought to be between 3 or even 1,000 terabytes. The National Archives of Britain, containing over 900 years of history, only takes up 70 terabytes, making our brain’s memory power pretty impressive.
49 – The brain is much more active at night than during the day.
50 – Facial hair grows faster than any other hair on the body. if the average man never shaved his beard it would grow to over 30 feet during his lifetime, longer than a killer whale.
51 – Hair and Nails are not the living part of our body.
52 – Every day the average person loses 60-100 strands of hair.
53 – One human hair can support 3.5 ounces.
54 – The fastest growing nail is on the middle finger. And the nail on the middle finger of our dominant hand will grow the fastest of all. Why is not entirely known, but nail growth is related to the length of the finger, with the longest fingers growing nails the fastest and shortest the slowest.
55 – Human hair is virtually indestructible. Aside from it’s flammability, human hair decays at such a slow rate that it is practically non-disintegrative.
56 – The human heart creates enough pressure to squirt blood 30 feet.
57 – Women’s hearts beat faster than men’s. The main reason for this is simply that on average women tend to be smaller than men and have less mass to pump blood to. But women’s and men’s hearts can actually act quite differently, especially when experiencing trauma like a heart attack, and many treatments that work for men must be adjusted or changed entirely to work for women.
58 – Our left lung is smaller than our right lung to make room for your heart.
59 – Sneezes regularly exceed 100 mph. There’s a good reason why we can’t keep our eyes open when we sneeze–that sneeze is rocketing out of our body at close to 100 mph. This is, of course, a good reason to cover our mouth when we sneeze.
60 – Coughs clock in at about 60 mph. Viruses and colds get spread around the office and the classroom quickly during cold and flu season. With 60 mph coughs spraying germs far and wide, it’s no wonder.
61 – A full bladder is roughly the size of a soft ball. No wonder we have to run to bathroom when we feel the call of the wild. The average bladder holds about 400-800 cc of fluid but most people will feel the urge to go long before that at 250 to 300 cc.
62 – Feet have 500,000 sweat glands and can produce more than a pint of sweat a day. With that kind of sweat-producing power it’s no wonder that our gym shoes have a stench that can peel paint. Additionally, men usually have much more active sweat glands than women.
63 – Babies are always born with blue eyes. The color of your eyes depends on the genes we get from our parents, but at birth most babies appear to have blue eyes. The reason behind this is the pigment melanin. The melanin in a newborn’s eyes often needs time after birth to be fully deposited or to be darkened by exposure to ultraviolet light, later revealing the baby’s true eye color.
64 – After eating too much, our hearing is less sharp. If we’re heading to a concert or a musical after a big meal we may be doing ourself a disservice. Try eating a smaller meal if you need to keep your hearing pitch perfect.
65 – Women are born better smellers than men and remain better smellers over life.
66 – Even small noises cause the pupils of the eyes to dilate. It is believed that this is why surgeons, watchmakers and others who perform delicate manual operations are so bothered by uninvited noise. The sound causes their pupils to change focus and blur their vision, making it harder to do their job well.
67 – The ashes of a cremated person average about 9 pounds. A big part of what gives the human body weight is the water trapped in our cells. Once cremated, that water and a majority of our tissues are destroyed, leaving little behind.
68 – By 60 years of age, 60-percent of men and 40-percent of women will snore. Normal snores average around 60 decibels, the noise level of normal speech, intense snores can reach more than 80 decibels.
69 – A baby’s head is one-quarter of it’s total length, but by age 25 will only be one-eighth of its total length.
70 – Monday is the day of the week when the risk of heart attack is greatest. A ten year study in Scotland found that 20% more people die of heart attacks on Mondays than any other day of the week. Researchers theorize that it’s a combination of too much fun over the weekend with the stress of going back to work that causes the increase.
