The Human body is the most amazing machine of nature, in a single human body there are different functions equivalent to the processes taking place in thousands of factories, even the scientists of the whole world together cannot create a machine like the human body. The human body is so amazing and miraculous that every part of it is full of mystery. Come! Let's discuss important and surprising facts about the human body and its parts...

Value of human body
Although the human body is not available for sale, but this body cannot have any value, because it cannot be made in any factory, yet every organ which can be transplanted on its basis like kidney transplant. The cost is Rs 10 to 25 lakh. The cost of liver, heart and tooth transplantation is in lakhs of rupees, thus if we talk about the cost of transplantation then it is also in hundreds of crores and scientists estimate that if this human body is made in a factory, So its price can range from around Rs 400 crore to Rs 1 lakh crore, this is the estimate of scientists.

Some facts about human body
Cells basic unit of life
Cells are the basic unit of life, all living things are made of cells. In a human body, about 30 crore cells die in 1 minute, that is, about 1.2 kg of cells die in a day and the same number of cells are born. There are about 50 lakh hair follicles on the human body and the number of hair on the head is about 90 thousand to 1.5 lakh, out of which on an average 50 to 100 hairs fall every day and the same number of new hairs are born till puberty.

DNA is the essence of life
The human body is made up of cells and DNA. There is a nucleus inside every cell and inside every nucleus there are chromosomes. Chromosomes contain a complete set of programming to create and maintain us, and these little chemicals are made up of DNA. DNA is said to be the most extraordinary molecule on earth that holds all our genetic information. It involves genetic programming that ensures that living beings can develop, survive, and reproduce properly. There is so much complex DNA inside the human body that if they were lined up in a straight line, it would be more than 620 crore kilometers long and this is enough to cover the distance from the Earth to the Sun more than 41 times.

Storage capacity of DNA
Scientists believe that approximately one gram of DNA can store 215 million gigabytes of data and an amount of DNA smaller than a sugar cube can store all the movies ever made. A container of DNA the size of a two-passenger van could store all the data the world has ever created.

Our body is home to several trillion bacteria
There are about 10 quadrillion cells in each human body but about 100 quadrillion bacterial cells. In short, they are a big part of us, or from the bacteria's point of view, we are a small part of them.
Bill Bryson, A Short History of Nearly Everything (2003)
(1 quadrillion = ten thousand lakh crore)

We should always remember that without bacteria we cannot survive even for a day on this earth. On the skin of a healthy human being (if he maintains average cleanliness), there are about one trillion i.e. one lakh crore bacteria which feast on about ten billion i.e. one thousand crore scales that fall from our skin every day. Not only this, they also enjoy the delicious oils and minerals that come out of our pores and cracks.

•     These are only the bacteria living in our skin, apart from this, bacteria are also present in our intestines and nostrils, on hair and eyelashes, on the surface of the eyes and in the mouth.
•     There are approximately 100 trillion or 100 lakh crore bacteria in our digestive system.
•     A single human being has more bacteria in his mouth than the population of this earth, that is, more than 800 crore bacteria are present in the mouth of a human being.
•     The speed of human sneeze can be more than 150 kilometers per hour.
•     Human hair can lift 500 times more than its own weight.
•     The most powerful muscle in the human body is his tongue, which has more than 2000 taste buds through which taste is detected.
•     To take even one step, a human being has to take the help of more than 200 muscles of the body.
•     More than 700 enzymes are active in the human body. The digestive juice produced in the stomach of the human body contains hydrochloric acid. This acid is so sharp that it can melt even a metal like iron.
•     99% of the calcium in the human body is found only in teeth and bones. The smallest bone in the human ear is the stapes, which is only the size of a grain of rice.
•     There are 300 bones in the body of a newborn baby at the time of birth and after growing up, these bones are reduced to only 206.
•     The bones of the human body are so powerful that a steel rod of the same size is five times stronger than steel, but the bones of the human body are more brittle than steel, due to which they break quickly when hit.
•     The human thigh bone, which is called the femur, is the longest bone in the body and it is so powerful that it can bear up to 30 times the weight of the human body.

Amazing facts about heart and brain
A human heart beats 1,03,680 times a day at an average rate of 72 beats per minute. Thus, in his average life span of 70 years, the human heart beats approximately 300 crore times. Our heart pumps about 7,500 liters (or 2,000 gallons) of blood throughout the body every day.

•     If we laid out all the blood vessels in an adult's body in a straight line, they would stretch for approximately 60,000 miles (or 96,560 kilometers). This is enough to circle the Earth more than twice. The diameter of our Earth is 12,742 km and circumference is 40,075 km.
•     Our brain consumes as much energy as is required to light a 10 to 12 watt bulb.
•     The memory power of this 1200 to 1400 gram brain of ours is so much that information i.e. data equal to 2.5 petabytes (2.5 million GB) can be stored and those who are spiritual yogi mahatmas have developed their brain through pranayama and meditation. They have done many TB can store information up to. 

•     More than 1 lakh chemicals are produced in the human brain every second.
    Processes take place, 80% of the heat from the human body comes out through the brain.
•     About 80% of the human brain is water and it contains about 8600 to 10,000 crore neurons, whichñ are connected to each other by about a hundred trillion sensory wires and exchange information between the brain and other organs through the ninth impulse at a speed of 268 miles (about 431 kilometers) per hour.
•     The lens of the human eye is 576 megapixels. The human eye is such a miraculous lens that it can distinguish more than one million colors.

Amazing facts about liver and kidney
•     Liver performs more than 500 functions in our body. Liver is an organ of our body which regenerates itself if a part is cut or destroyed.
•     The kidneys filter approximately 150 to 180 liters of blood per day and produce 0.94 to 1.7 liters of urine.
•     There are 10 to 20 lakh nephrons in the human kidney which work to control the balance of electrolytes and acids and alkalis and control blood pressure.

Amount of other substances in the human body:
 
Amount of calcium
The total amount of calcium in a person's body is about 25-30 grams at birth and about 1000-1500 grams in an adult. More than 99% of the calcium in the human body is stored in bone tissue and teeth.

Iron content
On average, an adult man's body usually contains about 3.5 to 4.5 grams of iron while an adult woman's body usually has a slightly lower amount, about 2.0 to 3.5 grams. Most of the iron in the body is found in red blood cells, where it is an important component of hemoglobin.

Magnesium
Magnesium is essential for many chemical reactions in the body. It helps in formation of bones and teeth. The human body contains about 25-30 grams of magnesium. Healthy men need about 420 mg and women need about 320 mg of magnesium on a daily basis.

Copper
The human body contains small amounts of copper. It is an essential mineral that plays a variety of roles plays in physiological processes Copper plays an important role in iron metabolism and the immune system and helps form red blood cells. On average, an adult human body contains about 50 to 120 mg of copper. Which is equal to 2 to 3 grains of wheat.

Iodine
The human body contains small amounts of iodine. An essential mineral found primarily in the thyroid gland. Iodine plays an important role in the synthesis of thyroid hormones. On average, an adult human body contains about 15 to 20 mg of iodine.

Phosphorus
Phosphorus is an essential mineral in the human body. Hydroxyapatite is a crystalline mineral found mainly in bones and teeth. Phosphorus helps build and protect bones and teeth. Phosphorus makes up about 1% of the total weight of the human body. About 85% of phosphorus is found in the skeleton and teeth as calcium phosphate crystals, 14% in soft tissues, and the remaining 1% in body fluids. The adult human body contains about 560 grams to 850 grams of phosphorus.

Potassium
Potassium balances fluids in the body. Helps in maintaining steady heartbeat and sending nerve impulses. The total amount of potassium in the adult body is approximately 45 millimoles (mmol)/kg body weight (about 140 grams of potassium is required for an 80 kg adult.

Sodium
The average amount of sodium in an adult male is 92 grams, of which about 35 grams is found in the skeleton. Sodium balances fluids in the body. Helps in sending ninth impulse.
