how do i fart?

Answer 1

Flatulence is the presence of gas under some degree of pressure, in a confined space. The term is normally used of the presence of gas in the digestive tract of mammals. However, a balloon is flatulent as is a fizzy drink until the gas is released by opening the bottle containing it. Though confused by the word's use as a euphemism for 'fart', flatulence is distinct from flatus, which is the release of such confined gas. The distinction becomes very important in cases of bloat. In the animal digestive tract, the gas is produced by symbiotic bacteria and yeasts.


Vocabulary:
Flātus is a Latin word meaning a puff or blowing of a gas such as air. Flatulence is a French noun derived from flātus, which as a medical term means 'accumulation of gas in a natural cavity'. More generally, flatulent means 'of a windy nature' or 'full of air and wind'. By extension, foods such as beans may be called 'flatulent', as they generate gas in the digestive tract which then becomes flatulent as it is liable to produce flātūs - puffs, blows and breathing, via the œsophagus (gullet) and mouth or via the anus. Flatulence is therefore a tendency to produce puffs and blows so the word can be applied to the character of a haughty person or to the wolf of the Three Little Pigs story, as well as to the more usual use in alluding to a physiological tendency to break wind.

Physiological processes:
The average human releases 0.5 to 1.5 litres (1 to 3 U.S. pints) (measured at NTP) of flatus a day by flatulating 12 to 25 timesThe primary constituents of flatulence are the non-odorous gases nitrogen (ingested), carbon dioxide (produced by aerobic microbes or ingested), and hydrogen (produced by some microbes and consumed by others), as well as lesser amounts of oxygen (ingested) and methane (produced by anaerobic microbes). Odors result from trace amounts of other components (often containing sulphur, see below).


Composition of flatus gases:
Nitrogen is the primary gas released. Methane and hydrogen, lesser components, are flammable, and so flatulence is susceptible to catching fire. Not all humans produce flatus that contains methane. For example, in one study of the feces of nine adults, only five of the samples contained bacteria capable of producing methane. Similar results are found in samples of gas obtained from within the rectum. The gas released during a flatus event frequently has a foul odor which mainly results from low molecular weight fatty acids such as butyric acid (rancid butter smell) and reduced sulfur compounds such as hydrogen sulfide (rotten egg smell) and carbonyl sulfide that are the result of protein breakdown. The incidence of odoriferous compounds in flatus increases from herbivores, such as cattle, to omnivores to carnivorous species, such as cats. Flatulence odor can also occur when there is a number of bacteria and/or feces in the anus while being expelled. A small amount of solid or liquid fecal matter in fine particulate aerosol form may also be expelled, and included, along with flatulence.


Causes:
Intestinal gas is composed of 90% exogenous sources (air that is ingested through the nose and mouth) and 10% endogenous sources (gas produced within the digestive tract). The exogenous gases are swallowed (aerophagia) when eating or drinking or during times of excessive salivation (as might occur when nauseated or as the result of gastroesophageal reflux disease). The endogenous gases are produced as a by-product of digesting certain types of food.

Flatulence producing foods are typically high in polysaccharides (especially oligosaccharides such as inulin) and include beans, lentils, milk, onions, radish, sweet potatoes, cheese, cashews, broccoli, cabbage, Jerusalem artichokes, oats, yeast in breads, etc. In beans, endogenous gases seem to arise from oligosaccharides, carbohydrates that are resistant to digestion. These pass through the upper intestine largely unchanged, and when they reach the lower intestine, bacteria feed on them, producing copious amounts of flatus (McGee 1984 pp.257–8).In the case of those with lactose intolerance, intestinal bacteria feeding on lactose can give rise to excessive gas production when milk or lactose-containing substances have been consumed.

Interest in the causes of flatulence was spurred by high-altitude flight and the space program; the low atmospheric pressure, confined conditions, and stresses peculiar to those endeavours were cause for concern (McGee, 1984 pp.257–8).


Mechanism of action:
The noises commonly associated with flatulence are caused by the vibration of the anus. The sound varies depending on the tightness of the sphincter muscle and velocity of the gas being propelled, as well as other factors such as moisture and body fat. The pitch of the flatulence outburst can also be affected by the anal embouchure. Among humans, sometimes farting happens accidentally, such as incidentally to coughing or sneezing; on other occasions, intentional farting occurs through the tensing and releasing of the anal sphincter.

Flatus is brought to the rectum in the same peristalsis method as feces, causing a similar feeling of urgency and discomfort. Nerve endings in the rectum learn to distinguish between flatus and feces, although loose stool can confuse these nerves, and sometimes results in accidental defecation.

Answer 2

Buy the book "farting for dummies"
Good luck

Answer 3

Buy the book "Farting for Idiots." It will explain everything.

Answer 4

you don't fart comes out for it self but when its coming you eill feel it or you can just push it

Answer 5

Just when I thought I couldn't read a stupider question on here, along you come and prove me wrong

Answer 6

Eat a lot of beans. And if you're lactose intolerant (meaning you can't eat/drink milk products without getting sick), sometimes drinking milk will give you gas (although it may also make you sick, so be careful).

Answer 7

lol when u feel air about to come out, push like the way u sh it and try to make it the loudest as possible!!! lol

Answer 8

push like your taking a crap... just stop before the crap comes out

Answer 9

eat taco bell

Answer 10

Fahrt from fahren, means to drive or go...
I assume you know how to do this.
