Farted.

 

but im not too sure.

 

Discuss.

 

 

Flatulence is the presence of a mixture of gases known as flatus produced by symbiotic bacteria and yeasts living in the gastrointestinal tract of mammals. Flatulence is released under pressure through the anus, often with a characteristic sound and offensive odor. Releasing flatulence is colloquially known as farting.

 

The average human releases 0.5 to 1.5 litres (1 to 3 U.S. pints) of flatus in 12 to 25 episodes throughout the day. The primary constituents of flatulence are the non-odorous gases, in descending order of concentration, nitrogen (ingested), oxygen (ingested), methane (produced by anaerobic microbes), carbon dioxide (produced by aerobic microbes or ingested), and hydrogen (produced by some microbes and consumed by others). Odors result from trace amounts of other components (often sulphur containing, see below).

 

Nitrogen is the primary gas released. Methane and hydrogen, lesser components, are flammable, and so flatulence is susceptible to catching fire. Gas released mostly 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.

 

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 nauseous 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, milk, onions, 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.

 

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.

 

The noises commonly associated with flatulence are caused by the vibration of the anal opening. 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.

 

Flatus is brought to the anus 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.

 

Certain spices counteract the production of intestinal gas, most notably cumin, caraway and the closely related ajwain, turmeric, asafoetida (hing) and konbu kelp (a Japanese seaweed). Many people report that by reducing intake of most refined carbohydrates (such as rice, pasta, potatoes and bread), the amount of flatulence may decrease significantly. The water-soluble oligosaccharides in beans that contribute to production of intestinal gas can be reduced through a regime of brief boiling followed by a long period of soaking, but at a cost of also leaching out other water-soluble nutrients. Some legumes also stand up to prolonged cooking, which can help break down the oligosaccharides into simple sugars. Fermentation also breaks down oligosaccharides, which is why fermented bean products such as miso and tofu are less likely to produce as much intestinal gas.

 

Probiotics (yogurt, kefir, acidophilus, bifidus, etc.) and prebiotics (such as FOS) may also reduce flatulence if they are used to restore balance to the normal intestinal flora; used in excess, however, they may create an imbalance which increases flatulence.

 

Medicinal charcoal tablets have also been reported as effective in reducing both odor and quantity of flatus when taken immediately prior to food that is likely to cause flatulence later.

 

Digestive enzyme supplements can significantly reduce the amount of flatulence that is caused by some components of foods not being digested by the body and feeding the microbes in the small and large intestines. The enzymes alpha-galactosidase (brands Beano, Bean-zyme), lactase (brand Lactaid), amylase, lipase, protease, cellulase, glucomylase, invertase, malt diastase, pectinase, and bromelain are available, either individually or in combination blends, in commercial products.

 

While not affecting the production of the gases themselves, surfactants (agents which lower surface tension) can reduce the disagreeable sensations associated with flatulence, by aiding the dissolution of the gases into liquid and solid fecal matter.

 

Often it is helpful to ingest small quantities of acidic liquids with meals, such as lemon juice or vinegar, to stimulate the production of hydrochloric acid, which in turn increases enzyme production. This facilitates digestion and may limit gas production.

 

As a normal body function, the action of flatulence is an important signal of normal bowel activity and hence is often documented by nursing staff following surgical or other treatment of patients. However, symptoms of excessive flatulence can indicate the presence of irritable bowel syndrome or some other organic disease. In particular, the sudden occurrence of excessive flatulence together with the onset of new symptoms provide reason for seeking further medical examination.

 

There is no particular harm to come from holding in flatus. Flatulence is not poisonous; it is a natural component of various intestinal contents. However, discomfort may develop from the build-up of gas pressure. In theory, pathological distension of the bowel, leading to constipation, could result if a person holds in flatus.

 

Not all flatus is released from the body via the anus. When the partial pressure of any gas component of the intestinal lumen is higher than its partial pressure in the blood, that component enters into the bloodstream of the intestinal wall by the process of diffusion. As the blood passes through the lungs this gas can diffuse back out of the blood and be exhaled. If a person holds in flatulence during daytime, it will often be released during sleep when the body is relaxed. Some flatus can become trapped within the feces during its compaction and will exit the body, still contained within the fecal matter, during the process of defecation.

 

The term meteorism is defined as the presence of gas within the abdomen or intestines. However, it is sometimes also used to describe the condition of excessive flatulence. Since subjective judgements vary considerably about what constitutes normal and elevated levels of flatulence, medical personnel sometimes instruct a patient complaining about excessive flatulence to maintain a personal flatulence diary. Researchers studying flatulence have also developed what is called a flatulogram. Its horizontal axis represents time (typically 24 hours, with each hour being marked on the time line). The subject is instructed to make a pencil mark on this line at each point in time that they notice flatus passing through the anus. The acoustic volume of the event is indicated by the vertical distance that the pencil mark rises above the time line. Inaudible events are indicated by a short mark that extends only below the time line.

OK LET ME REPHRASE

 

 

 

what did dumy start!?!?!?

 

WRONG AGAIN.

 

THREE STRIKES AND YOU'RE OUT.
