Because of the varying intensities of vibration caused by the fart passing through the membranes of the anus. Depending on the speed with which the gas is expelled and the contraction of the sphincters (valves that control the opening and closing of the anus), the fart will be loud or silent. Next, prepare the oxygen balloon and check out other curiosities about these infamous gases. =(~
BULLLER SYNDROME
Sound fart is the result of high gas pressure combined with the contraction of the fiofo
The gases accumulate at the end of the intestine, just before the anus, which is a kind of ring, with two valves (sphincters): the inner one opens involuntarily; the external one can be controlled and opened gradually. The expulsion speed of the wind depends mainly on the volume of gas and the pressure exerted by it: more pressure, greater speed. With the external sphincter contracted, the fart, which is coming out at full speed, generates a noisy vibration of this membrane as it leaves the fiofó. With the sphincter relaxed, the trach comes out smoothly, without making any noise.
HAJA NOSE!
Other things you need to know about “rojões”
IS IT POSSIBLE TO GENERATE ENERGY WITH FLATO?
In theory, yes, because about 10% of fart is made of methane, which is flammable. But for that to happen, it would be necessary to overcome several obstacles, such as the invention of a device that collects the gases directly from the source. Be that as it may, see below how you would fare at the “fart factory” post.
WHICH FOODS GENERATE MORE GAS AND WHY?
Tubers, some cereals, certain legumes and dairy products are the foods that most cause flatulence. This happens because these foods are not fully digested in the stomach and end up suffering the action of bacteria in the intestine with the consequent formation of gases. See the ranking of fizzy foods below.
1st TUBERS
Sweet potato and yam
2nd CEREALS
Beans and chickpeas
3rd VEGETABLES
Cabbage and cauliflower
WHO FARTS MORE: MEN OR WOMEN?
Neither. In this dispute it is a draw. “For cultural reasons, men have more freedom to eliminate flatus in public, which does not happen to women. They, out of modesty, tend to hold them and only eliminate them when they are alone”, says gastroenterologist Arnaldo Ganc, from Hospital Israelita Albert Einstein, in São Paulo.
IS A BURCH THAT COMES OUT OF THE MOUTH?
No, belching is not “a naughty fart who went up in an elevator”, as the popular saying goes. Here’s how it works: after air is swallowed, it passes through the pharynx and esophagus before reaching the stomach. Part of this air goes to the intestine, where it will turn. pum The other, driven by stomach contractions, takes the path back and comes out of the mouth in a beep! (Oops!)
WHAT IS PUM AND HOW IS IT MADE?
It’s a variable mixture of odorless gases, which we swallow throughout the day, and, of course, the smelly gaseous compounds produced in the intestines. With you, the script for the “super production” Nascido para Feder:
Most fart-forming gases, such as nitrogen and hydrogen, enter the mouth when swallowed during meals or when we talk. These gases travel through the digestive tract and part of them is absorbed by the body. The rest reaches the intestine, where it will thicken the trache. Foods that are not completely digested in the stomach, such as beans and sweet potatoes, are fermented by bacteria in the intestine, generating more gas, which is often stinky. This mixture of flatus accumulates in the intestine until it is finally expelled through the anus because of the pressure.
WHAT HAPPENS TO THE PUMP WHEN YOU HOLD IT?
He goes back to the gut, until he gets another chance to escape and conquer the world. Often the release happens at night when you are sleeping. According to doctors, there is no problem in trapping one trach or another, but those who do it frequently run the risk of having abdominal distention and stomach aches.
CAN YOU LIGHT A FART?
Yes, because methane, one of the trach gases, is flammable. There are even reports of people who suffered burns during surgery on the intestine, when the methane from the flatus became inflamed with the use of the cauterizer (a kind of blowtorch to heal ruptured vessels). So beware: if you’re one of the clueless ones who play at lighting farts, you might end up with a toasted ass!
WHY ARE THEY STINKY?
Because of malodorous compounds, such as sulfur, fatty acids and sulphides, produced during the process of digestion of food by bacteria present in the intestine. Eggs and meats generate smelly firecrackers because they are rich in protein, whose fermentation produces large amounts of sulfur and hydrogen and carbon sulfides, which smell like rotten eggs. Fatty foods are also champions of stink, as they cause the formation of large amounts of fatty acids, another non-aromatic substance.
WHAT IS OUR DAILY FART PRODUCTION?
Around 1 liter to 1.5 liters, distributed in 15 to 20 farts. “They are released at any time of the day or night, whether we are awake or asleep”, says general surgeon André Martins Barros, from Hospital Sepaco, in São Paulo. Everyone farts – even the hottie at school. What’s more, some people fart even after they’re dead!
