Amazing Things Done By Human Body That Are Beyond Science

Human body is a mine of many wonders and amazing facts which you never observed in detail.But these facts can be observed in our day to day life. amazing things done by human body that are beyond science

Some of them are brought to you by Vulguss .

01.Complexity of Eye Movements
Look at an object on the wall across the room. Now keep looking at it while you move your head back and forth, up and down. Your eyes stay pointed at that spot. Not hard to do, is it?

 Your brain needs to calculate the direction and rate of change your head is moving in 3 dimensional space. Now the brain send corresponding signals to the muscles in your eyes that do exactly counter match the rotation and speed in order to keep them pointed at that spot.

Also the muscles that have to be moved (and the rate at which they move) are different for each eye, since if you turn your head quickly right, you right eye contracts the muscles on the nose side to compensate, and the left eye contracts the muscles on the temple side.

 It’s an absolutely amazing, fine-tuned process involving incredible spatial calculations and microsecond signaling and adjusting that we do all the time and take completely for granted.

02.Our Running Abilities
Humans can outrun most animals in long distances due to our ability to cool and our efficient 2-legged running. Because this is the way to hunt (and it still practiced in VERY small parts of the world). It’s called persistence hunting. 

Basically, humans can control the heat while running/jogging/walking, whereas the animals doesn't have this ability(antelope for example). They cannot regulate their heat efficiently. The hunter keeps the animal in sight,and will give a chance of resting to the animal. Eventually, the animal either dies of heat exhaustion, or is just too exhausted to continue running away, and the hunter can easily kill it with a spear at close range. It is insane to think that your body is able to run an animal to death. 

03.Dexterity of Hands and Fingers
The human hand is one of the most insanely fine-tuned pieces of organic machinery on the planet. It contains an absurdly dense amount of nerve cells and special nerve adjustments that make it incredibly sensitive to extremely small signals.
The natural craftsmanship of our hands has a dexterity for precision that other apes do not have. Human fingers can feel objects as small as 13 nanometers. This means that, if your finger was the size of the Earth, you could feel the difference between houses from cars.
 Amazing fact is human fingers contain no muscles. They are solely controlled by muscles in the arm and palm pulling on tendons.

04.Fetus’ Superhuman Abilities
When a pregnant woman suffers organ damage (such as a heart attack), the fetus sends stem cells to the damaged organ to help repair it. Doctors have observed that women who experience weakness of the heart during pregnancy or shortly after giving birth have better recovery rates than any other group of heart failure patients.
 A study suggests that fetal stem cells may help human mothers, as well as infant, recover from heart damage. It may also explain another curious clinical observation: The hearts of two women who suffered from severe heart weakness were later found to contain cells derived from the cells of a male fetus years after they gave birth to their sons. The same thing seems to hold true for other organs. When pregnant women have damage in other organs, including the brain, lung, and liver, earlier studies have shown, fetal cells show up there, too.

05.Body Destroying Cancer Cells

Each day, your immune system spots and destroys cells that could easily go on to become cancerous. The irony is that both mutant and hunter come from the same source – the immune system. In this way, it could be argued that everyone gets cancer and beats it. Also when you get a sunburn, it’s not your skin cells being damaged by the sun and dying, it’s your skin cells’ DNA being damaged by the sun and them killing themselves so that they don’t turn into cancer.

06.Complexity of Breastmilk Production
Breastmilk actually changes its composition to meet the individual nutritional needs of the baby(ies) feeding from the breast. For example, if mom is feeding a toddler, the child gets a full session’s worth of proteins, fats and vitamins in their one minute feeding, the same as a 3 month old gets in their 25-minute session. 
As they get older, the quantity of vitamins, fats and proteins changes as well to meet their individual needs. This is even true if mom is feeding two babies of different ages then the milk actually customizes itself to ensure that they both get exactly what they need, and the amount of milk she makes is dependent entirely on how much stimulation she gets (i.e. the more the baby nurses at the breast, the better supplied they are. This is why using bottles and pacifiers mucks up someone’s supply because the baby wastes all their suckling needs somewhere else). The milk makes antibodies for the viruses mom and baby are exposed to and fighting off.

       The coolest part in particular is that before the mom even knows she or her baby are sick, her milk is already creating medicine (antibodies) to treat her child. It’s like a built-in vaccine that is constantly being updated to fight off the latest bugs. This is the main reason why breastfed babies are better equipped to fight off both short-term illness and long term disease (like respiratory illness, asthma, allergies, etc). Breast milk is also amazing because within the first 1-3 days of a newborn feeding, the milk is actually close to clear in its color due to the fact that it is mostly antibodies preparing the baby’s immune system. In the last few weeks of pregnancy, the mother’s body will “fill” the baby with essential nutrients and minerals, allowing the first few feeds to have a little less nutrient and a little more antibodies. This is called Colostrum(liquid gold). Colostrum is known to heal skin burns and tears faster. Apparently, if you put breast milk in your eye during an infection, it will heal quicker. Same is true with ears.

07.Energy Production via Mitochondria

Mitochondria have different DNA from the human body, which likely stems from the fact that they were once bacteria internalized by another single cell organism (probably archaea) very early on in the evolutionary process creating the single most important symbiotic relationship. Mitochondria are responsible for all of the energy production in your body. Mitochondrial DNA is also inherited from only the mother. It has very low evolutionary pressure and can be used to track ancestry very far back.

08.Body’s Resilience

The resilience of the human body is pretty damn incredible. Your body will fight with every ounce of its being to keep you alive, literally. Your body will digest itself to salvage nutrients for vital organs. Your cells will kill themselves if they can tell there’s something wrong with them for the good of the rest of the body, and you have so many reflexes that you wouldn’t even begin to understand them until they actually kicked in when you go into survival mode. The instinctive drowning response, for example. Every part of your body is focused on keeping your mouth above water for air. My personal favorite response is fight or flight. Normally your muscles are limited in how much power they can exert so that they don’t get hurt excessively during routine tasks like exercising. When your adrenaline surges, that limit is gone. Your muscles will work as hard as they possibly can without restraint, and you don’t feel the pain of overexertion either. This is where we get those stories of people lifting cars off their children – hysterical strength.
