What animal farts stink

Just ask the weasel fart! Farts are exhaust gases emitted by the body, mostly carbon dioxide, hydrogen, and methane. In the past, it was a common belief that the smell of farts was emitted by methane.

Actually, methane itself doesn't stink. Modern science has proved that the "culprit" of odor is indole, skatole, hydrogen sulfide and other foul-smelling gases.

Because the human sense of smell is particularly sensitive to these gases, even if someone secretly farts in the public, the result can still be quickly detected by people and cover their noses and shout smell! Farts are produced because some of the food we eat is not broken down. The unbroken down parts, including fiber and sugars, become food for coliform bacteria.

When coliform bacteria are full, they are vented, and these gases accumulate in the body, creating a burst of air pressure. When the pressure is too high, it is expelled from the body and a fart is formed. The amount of fart is related to what people eat.

Some people love onions, ginger, garlic, potatoes, sweets, beans and pasta, because these foods contain a matrix that produces a lot of hydrogen and carbon dioxide, hydrogen sulfide and other gases. The number of farts is also related to the strength of a person's digestive function. When indigestion occurs, intestinal bacteria ferment quickly, and it is easy to produce gas and cause people to fart.

A scientist found that a person farts about 14 times a day. Every day, each person releases about 500 milliliters of exhaust gas. Although farts stink, farting is a normal physiological need, and it is beneficial to people's health.

A person who doesn't fart all day long is not good for health. People who never fart all year round are most likely to have a problem with their gastrointestinal tract. Drinking a cup of yogurt every day can help change the bacteria in the gastrointestinal tract.

In the large intestine, especially from the large intestine to the rectum, there are about 100 species of 100 trillion bacteria, which make food easy to decompose, and in the process of food decomposition, harmful gases are produced, and these harmful gases are concentrated and excreted from the body to become farts. The most important component of the fart is nitrogen, accounting for about 80%; This is followed by carbon dioxide.

2% to 19%; And hydrogen, methane.

oxygen, etc. Of the above-mentioned substances, odorless gases account for 99%. In addition, indigestion.

Due to the slow decomposition of food in the gastrointestinal tract, it will also produce a large amount of foul-smelling gas, which will be discharged in stages, although it is not "loud", but it is very smelly. The composition of farts is related to the type of food, such as eating potatoes or turnips, which produce a lot of carbon dioxide gas during the decomposition process, and these farts tend to be thunderous but not too smelly. Conversely, if too much protein, garlic, beans and other foods are consumed, hydrogen sulfide will be produced.

Indole (an organic compound found in coal tar and putrefactive proteins) and foul-smelling substances such as skatin make such farts smell unpleasant.

The smelliest animal in the world: a fart can pollute a radius of 800 meters, and can seriously cause blindness.
