8 information as true as it is disgusting about the human body

The human body is an incredibly well-oiled machine, but sometimes not very tasty. The veil is lifted on a few oddities of the organism which will astonish the common mortal.

We produce 55 kg of stool per year

Excrement, composed of water (75%!), Dead bacteria and food residues not absorbed by the digestive system, each adult in the product between 150 and 200 grams per day on average, or at least 55 kilos per a. At the scale of the world’s population, this corresponds to 11 tons of feces discharged every second. A statistic that can be followed directly here.

It is possible to vomit your excrement

We remain on the subject of stool with a fortunately very rare anecdote: it is possible to vomit his excrement. A digestive disorder called fecaloid vomiting (or “purée de poix”) and caused by a rise in intestinal secretions in the stomach, itself due to an occlusion in the intestine or serious pathologies such as cancer.

We produce 1.5 liters of saliva per day

Between 2 and 4 pints of saliva: this is what an adult produces every day on average, the equivalent of about 45,000 liters in a lifetime – enough to fill a pool. And that’s a good thing, because saliva is needed for swallowing and digestion, protects teeth from mouth acidity, cleanses the palate and contributes to the taste sensation. Bonus info: notre saliva contains opiorphine, a 3 times more effective substance, which is morphine against pain and without side effects.

We have 2 kg of bacteria in us

The intestinal microbiota (formerly called the intestinal flora) includes at least 100,000 billion bacteria, for a total of two kilograms, perfectly useful to our body. It is roughly twice the number of stars in our galaxy. There are more bacteria in our mouths alone than humans on Earth. By comparison, our body has ten times fewer cells (10,000 billion) than bacteria.

Our eyelids and eyelashes are home to little beasts

Demodex mites live in our lashes and eyelids: they eat dead skin cells, reproduce and die. Most of the time, it helps to cleanse the skin, especially the sebum. They can, however, proliferate without common measure if the lashes are not properly cleaned, and lead to an infestation.

Women can secrete breast milk through the armpits

During pregnancy, it is natural to have breasts soaked in breast milk, but it is not impossible to also secrete them … through the armpits. This happened to Linda Jones, a 39-year-old mom who, after giving birth to triplets, saw her breast tissue swell and spread to her armpits. A phenomenon she relayed on social media, before the media got involved. Even rarer, a young mother even reported secreting breast milk through the vulva.

We can sweat up to 10 liters a day

Normally, the body of daily product between 0.5 and 1 liter of water, composed of 99% water, especially minerals such as sodium (which gives it a salty taste), and organic compounds. Une bonne suée can hold up to 10 liters in case of high heat, intense physical exertion, fever or great stress. Note that, contrary to popular belief, sweat does not smell: it is its decomposition, by bacteria living on the surface of the skin, that is the cause of its pungent odor.

We can perpetuate up to 50 km / h and up to 9 meters away

According to a recent study, when a person sneezes, the air is expelled through his nose at an average speed of 16 km / h, and up to 50 km / h in some, slightly higher than the air released in case of cough. Under the circumstances, sneezing can project fluid nine meters away. But that’s only if you don’t put your hand in front of your mouth.
