Many changes occur in our bodies, that we have no idea about. it may be the height growth in the morning, heartbeat, blood supply, eyes blink, and so on. Our body is a beautiful, awesome machine. we have no idea about the internal organ’s performance.

Our body is composed of cells, tissues, organs, and systems. in this blog let us explore interesting and amazing facts about the human body which we might not know earlier.

1. Fingernails grow faster than toenails.

Fingernails grow as faster as toenails. because Nails contain a protein called keratin. Each nail begins growing out of a little pocket under your skin. this is called the nail matrix. The matrix is constantly making new cells. and pushing the older ones up. and the little patch of skin under the nail is called a nail bed. Once those cells are pushed out of your skin. they’re already dead. which is why it doesn’t hurt to cut your nails.

fingers are used so much more often than your toenails. the nails of your fingers grow faster than your toenails.  fingernails are closer to our hearts. and therefore have increased blood flow. which may be a factor in their rate of nail growth as well. 


2. Lungs are the only organ that floats on water.

Lungs are able to float on water because the lungs have millions of air-balloons called alveoli. the role of alveoli is to replace the carbon dioxide waste in the body with oxygen. when lungs are filled with water they are able to float!

 According to a 2013 study in the International Journal of Legal Medicine. A lung float test is conducted in pregnant women to determine the baby stillborn. if the lungs float then the baby is alive.

The lung on the left side of your body is divided into two lobes while the lung on your right side is divided into three. The left lung is also slightly smaller, allowing space for your heart.

3. The cornea has no blood supply!

Because of transparency. the cornea does not have blood vessels; it receives nutrients via diffusion from the tear fluid at the outside and the aqueous humor at the inside and also from neurotrophins supplied by nerve fibers that innervate it.

6. The brain is the Fattest organ!

The brain contains 60% of fat. And it is one of the fattest organs in the body. The brain is the most important organ in the body. It helps us think, remember, and learn new things. Even though it has fat it still works hard. it can generate 25 watts of power. which is needed for the lightbulb.


7. The average person has 100,000 – 150,000 strands of hair.

Hair count varies from individual to individual. it also differs in hair color. male hair grows faster than female hair. if a hair is lost then it grows immediately. it is estimated that it grows 1/2 inch per month :-). wet hair can stretch 30% longer. on average hair is nearly 100,000 t0 150,000.

The hair on our bodies helps us to do many functions. It helps to protect us from the dust, to regulate our body temperature, and to perceive sensations.

8. We have 12 million smell receptor cells.

The olfactory receptor is also called a smell receptor. it is a protein that plays a vital role in the sense of smell (olfaction). These receptors are also found in common in arthropods, terrestrial vertebratesfish, and other animals. humans have 12 million smell receptors.

12 million means a large number of receptors, but few animals like rabbits have about 100 million, dogs have about 1 billion. Dogs are used to identify criminals with the smell.

9. We Can’t See Taste Buds.

Yes! we are unable to see the taste buds. we cannot see taste buds with our naked eye. we actually see pink papillae. most of the taste buds are at the tongue. we generally assume that tongue has 4 tastes sour, bitter, sweet, and salty. but savory is another taste. the tongue helps us in living.


10. Skin weighs 15% of body weight.

our skin is the largest organ. it plays a vital role in detecting hot and cold. it also helps in regulating our body temperature and protecting our muscles. the skin protects bones and internal organs from infection and disease. The skin grows every 28 days. most of the bacteria are present on the skin.

even though the skin is only a few millimeters thick. The thinnest part of the skin is found on eyelids measuring at 0.02mm thick. And the thickest on your feet measured at 1.4mm. Skin is made up of multiple layers of cells and tissues. This is held to underlying structures by connective tissue.
