The human body is the scene of many fascinating scientific discoveries. Let us discuss some of the most interesting facts about the human body.
Interesting Human Being Facts
👉 The appendix is one of the vestigial organs of the human body
The appendix has a poor reputation. It is typically regarded as a physical part that no longer serves any purpose. It only ever seems to become infected and results in appendicitis occasionally.
However, the appendix has recently been found to be extremely beneficial to the microorganisms that keep your digestive system running smoothly.
They use it as a place to reproduce and replenish the gut’s bacterial population while taking a break from the strain of the organ’s frenetic activity. Therefore be respectful of your appendix.
👉 The chromosome may be called the largest molecule.
Almost everything we encounter is composed of molecules. They come in various sizes, from straightforward atomic pairs, like oxygen molecules, to intricate organic structures. The largest molecule in nature, however, is found in your body. First chromosome.
A typical human cell contains 23 pairs of chromosomes, each of which is a single, extremely long DNA molecule.
With over 10 billion atoms, chromosome 1 is the largest and contains most information stored in the molecule.
👉 How many atoms make up one adult human?
Until you see how many atoms there are in your body, it isn’t easy to appreciate how little they are. Around 7,000,000,000,000,000,000,000,000,000 (7 octillion) atoms make up one adult.
👉 The number of hairs in the human body is the same as of a chimpanzee.
We have almost the same number of hairs on our bodies as chimpanzees, even though they are useless and so fine that they are essentially invisible.
We don’t exactly know what caused us to lose our protecting fur. It has been hypothesized that this may have occurred because our predecessors were somewhat aquatic, assisting early humans in sweating more easily or making life more difficult for parasites like lice and ticks.
👉 How did we develop goosebumps?
Goosebumps are a legacy of our extinct ancestors. They develop due to the base of each hair’s small muscles tensing and drawing it more upright.
This would fluff out the coat, allowing more air to enter it and improving its insulating properties with a good coating of fur. But, a human’s sparse body hair only makes our skin appear odd.
👉 Your body can barely resist the discomfort in space
If science fiction movies were to be believed, if your body were pushed off a spaceship without a suit, awful things would happen.
But most of it is made up. Although there wouldn’t be anything like the exploding body parts Hollywood adores, there might be some discomfort as the air inside the body expands.
Although liquids boil in a vacuum, your blood would be alright since your circulatory system maintains pressure.
Furthermore, despite the extreme cold in space, you wouldn’t lose heat very quickly. A vacuum is a fantastic insulator, as Thermos flasks show.
👉 The human body can become microscopic by nuclear collapse.
Despite having a large number of atoms, your body would compress into a very small volume if it weren’t for the fact that the majority of them are empty spaces.
The size of a fly in a cathedral can be used to compare the size of an atom’s nucleus, which makes up most of its stuff.
Your body would fit into a cube with less than 1/500th of a centimeter on each side if you lost all of your empty atomic space.
👉 The atoms in our body and the atoms outside are electromagnetically repelled.
Never do the atoms that make up matter come into contact. The electrical charges on their individual pieces repel one another more strongly the closer they get.
It’s comparable to attempting to align the north poles of two incredibly potent magnets. This holds true even when it appears that two items are touching.
You don’t touch a chair when you sit on it. You are suspended by the attraction between atoms a short distance above.
👉 The human body is made up of stardust. But how?
Your body’s atoms are billions of years old. The most prevalent element in the universe and a crucial component of your body, hydrogen, was created in the big bang 13.7 billion years ago.
Between 7 and 12 billion years ago, heavier atoms like carbon and oxygen were created in stars and launched into space when the stars exploded.
A few of these explosions were so potent that they also created elements heavier than iron, which stars cannot produce.
This means that because you are made of stardust, the parts of your body are actually very old.
👉 The atomic structure of the human body resembles the solar system.
One of science’s greatest mysteries is how something as seemingly simple and substantial as your body can be composed of atoms and other quantum particles with peculiar behaviors.
When asked to sketch an image of one of their body’s atoms, most people would create something resembling a small solar system, with the nucleus serving as the sun and the electrons whirling around as planets.
👉 Porphyrin is actually responsible for red blood.
You might suppose that the blood on your finger that is bleeding is red because of the iron in it because rust has a crimson tint.
However, the iron’s presence is merely a coincidence. The iron in hemoglobin is bound in an atomic ring structure called porphyrin, and this structure’s shape gives the color red.
👉 The human body is an accumulation of various genes.
Interestingly, part of the valuable DNA in your chromosomes was borrowed from other species and did not entirely come from your evolutionary predecessors.
At least eight retroviruses have genes that are present in your Genome. They are a specific type of virus that use a cell’s DNA coding systems to take over a cell. These genes entered human DNA at some point in the course of evolution.
👉 There are many friendly bacteria inside the human body
There are more bacteria inside of you than there are human beings based solely on cell count. Your own cells number about 10 trillion, but bacteria are ten times more numerous.
In the sense that they don’t cause any harm, many bacteria that live inside you are friendly. Some are advantageous.
👉 The human body contains eyelash mites.
It is quite likely that you have eyelash mites, depending on your age. To survive, these tiny organisms feed on dead skin cells and sebum, natural oil secreted by human hair follicles.
Although some people may experience an allergic reaction, they are typically safe. Eyelash mites are usually a third of a millimeter long and nearly translucent, so it is doubtful that you can notice them with the unaided eye.
👉 The human eye can see Andromeda.
Just a few photons of light can be detected by your eyes because of their high sensitivity. On an extremely clear night, a small fuzzy patch of light is visible to the naked eye in the Andromeda constellation.
You are seeing as far as is humanly possible without the aid of technology if you can make out that small blob. The nearest big galaxy to our own Milky Way is Andromeda.
👉 There are more than five senses.
You have more than five senses, despite what you’ve undoubtedly been told. Here is an easy illustration.
A hot iron should be a few centimeters away from your hand. Your five senses cannot warn you that the iron will burn you.
But even from a distance, you can sense that the iron is hot, so you decide not to touch it. In an additional sense, the heat sensors in your skin are responsible for this. Similarly, we can feel pain or know when we are upside down.
👉 The human body starts as an egg.
Your life began with an egg, just like that of a chicken. An egg, however not a large object with a shell. A human egg and a chicken egg differ significantly in a way that has a startling impact on your age.
Human eggs are very few. These are only single cells, and they are typically 0.2 mm across or approximately the size of a printed full stop. Your mother gave birth to your egg, but what’s surprising is that she gave birth to it as an embryo.
👉 Biological influence is more responsible than the DNA
Although genes are commonly thought of as the deciding factor that defines how we look physically, they make up a very small portion of our DNA.
We now understand that epigenetics, or the activities that occur outside of the genes, also significantly impacts human development. The other 97% was previously believed to be useless.
👉 Consciousness exists directly in your body
If you’re like most people, you’ll think of your conscious mind as being roughly behind your eyes, controlling the much larger automaton that is your body, as if it were a little person sitting there.
Although you know that there isn’t really a small figure operating the levers there, your consciousness appears to exist independently and direct the rest of your body.
👉 Optic delivery is different in human beings.
The world that we “see” is a manufactured one. How a video camera creates an image is not how our brains do.
Instead, the brain creates a picture of the world using data from modules that measure light and shadow, edges, curvature, and other attributes.
