TOP THIRTY OF THE DAY

Top 30 fascinating things the human body can do

by Judith Lussier

The human body is an incredible machine, capable of miraculous feats. Here are 30 fascinating things that the human body can do.

  1. Regenerates

Several parts of the body can regenerate. Most notable is the liver, which can rebuild itself even when most of the organ is amputated. The skin is also in a constant state of regeneration, thanks to its progenitor cells which grow between the dermis and the epidermis. We lose and create new skin every day!

2. Reproduces

No one is indifferent when witnessing the fascinating phenomenon of reproduction, in which one sperm among millions manages to fuse with an egg and transform into an embryo that will eventually become a person.

  1. Cleans itself

Even though we are always trying out the latest detox products on them, our body’s organs are generally able to eliminate waste and toxins they are exposed to all on their own.

  1. Dissolves zinc

Stomach acid is a powerful biological agent with a pH low enough to dissolve metal. This means the body can also destroy most microbes.

  1. Lifts up 100 grams

The Great Antonio could pull a bus by his hair, which was truly impressive. But every human can hold up 100 grams (3.5 ounces) with a single hair, which is the equivalent of lifting two entire elephants with a head of hair!

  1. Integrates into another body

Thanks to scientific advances and the help of anti-rejection medication, organs from a human body can be integrated into another body via a transplant or a graft. This procedure can save lives.

  1. Fights the bad guys

Thanks to its antibodies, the body can defend itself against pathogens. The body can develop these little biological soldiers on its own, but sometimes it needs a little help in the form of vaccination to develop its response to certain diseases.

  1. Produces A LOT of saliva

The body produces approximately 30 ml (1 oz) of saliva per hour, the equivalent of a bottle of wine every day, or 53 bathtubs over the course of a lifetime. Technically, because we are always in the process of swallowing our saliva, the body is recycling rather than producing new saliva.

  1. Identifies a trillion smells

It’s hard to imagine, but the human nose can differentiate up to one trillion (a thousand billion) smells, thanks to its 400 types of olfactory receptors. Sounds impressive, but dogs can identify 40 times more smells than humans can!

  1. Creates light

We have something in common with the firefly: humans can create light! The human body creates light through incandescence, but this light is invisible to the naked eye. However, we can see it through a thermal imaging camera.

  1. Contains reserves

The human body manages its goods like a small business, and when it is missing something it digs into its reserves. For example, athletes understand the concept of glycogen stores that the body can call on during athletic performance. When we eat too many calories for our daily needs, the body stores them, for better or worse, as fat stores that it can call on if needed.

  1. Synchronizes with music

Our cardiovascular system synchronizes with the beat of the music, which can be beneficial to heart health.

  1. Dopes itself

Quadriplegic athletes are familiar with the phenomenon called dysreflexia. It is an excessive response from the body triggered by pain that, while not felt by the quadriplegic (whose sensory influx of pain is not transmitted to the brain), is recognized by the nervous system. This phenomenon acts a little like adrenaline, helping us achieve great feats when we perceive danger. It’s considered a form of doping by the International Paralympic Committee.

  1. Secretes powerful chemicals

The brain continually secretes neurotransmitters which are like doping products for the brain; they can boost our mood (serotonin), help our reaction to stress (adrenaline) or help us stay calm (gamma-aminobutyric acid).

  1. Continues to grow

Your nose and ears grow throughout your life. In reality they do not really grow, but the effect of gravity causes the cartilage they are made of to sag and therefore to stretch.

  1. Produces dust

The dust you clean indoors is made up of outside dirt, animal hair, and your own skin! Some say at a proportion of up to 70%, which is unlikely, since most dead skin cells wind up in the shower drain.

  1. Creates electricity

The body is its own little electricity generator and produces the electricity it needs for the brain to work properly. This electric current is what allows the brain to send messages throughout the body and to tell them what to do!

  1. Protects sperm

Sperm’s preferred temperature is 34.4 degrees Celsius (94 degrees Fahrenheit), slightly less than our body temperature, which is 37 C (98.6 F). The human body has a special tool to keep sperm at the perfect temperature: the scrotum, a muscular cover that keeps the testicles outside the body, and that pulls them inside when the temperature gets too cool.

  1. Hardens

The body adapts to your activities. That is why our skin develops calluses in areas where it is used often to provide greater protection. In the same way, if you work out, you will notice that it becomes easier as your body increases its breathing capacity and develops more muscles.

  1. Warms itself

The body has many ways to counter the cold. One example is the phenomenon of piloerection, commonly known as goose bumps, a reflex that uses the bumps to help maintain a layer of warm air above the skin. Of course, goose bumps are not helpful when it comes to keeping warm in the dead of winter!

  1. Gets rid of intruders quickly

The body doesn’t let everything get into your lungs, and the nerve endings in your nostrils sound the alert whenever there’s an intruder! Sneezing then helps push out impurities on a strong air current, driven by the diaphragm.

  1. Tells everyone when you’re embarrassed

The body can be a real tattle-tale. Sometimes it will betray the fact that you’re embarrassed by giving your skin an extra rosy tint. This is actually a sympathetic nervous system response which sends the body a message that could be translated as “Red alert, embarrassing situation! Need backup!”

  1. Produces unique traits

Just like snowflakes, every human is unique. This singularity is obvious in our fingerprints, which are as good as any ID. However, as with snowflakes, it is impossible to say with certainty that no fingerprints are alike, since it is impossible to compare the prints of every human on earth!

  1. Lifts its own weight

There is an Incredible Hulk living in every one of us. When under the effect of adrenaline, a hormone that is produced when we are under stress, our physical strength can increase by 35%!

  1. Moves air

Coughing may suck, but it’s also really impressive. This automatic reaction that helps clear out our lungs can move air at speeds of 80 km/hour (50 miles per hour). And a sneeze moves air twice as fast!

  1. Adapts to its environment

The human body adapts to its environment. For instance, people who live at high altitudes where atmospheric pressure is lower and oxygen rarer generally have greater lung capacity. Melanin, which is responsible for variations in skin colour, protects skin from ultraviolet rays.

  1. Passes on its defects

Thanks to natural selection, by which the most evolved species reproduce and pass on their physical traits to their offspring, species evolve so they are ever adapting better to their environment. But we also pass on our defects to future generations. Certain hereditary diseases such as deafness, Alzheimer’s and schizophrenia can be passed from generation to generation.

  1. Sends information very quickly

Information transmitted by our neurons travels at a speed of 430 km/h (268 mph)!

  1. Keeps us cool

Sweating is one of the ways in which the body helps maintain a temperature of 37 degrees Celsius (98.6 degrees Fahrenheit). Sweating helps by evacuating body heat through perspiration.

  1. Tells us lies

The brain can make us believe that we are sick (somatization) without physical proof, but can also make us believe enough in a medication that it actually heals us (placebo effect).

 

REMEMBER: The most wasted of all days is one without laughter.
