Question

how does fart form

Answer 1

Fart forms because of digesting food. Gas can be found all through the stomach related parcel, including the stomach, small digestive tract, rectum and colon.
It's the arrival of intestinal gas.Flatulence is formed of changing amounts of exogenous sources and endogenous sources.The exogenous gases are gulped (aerophagia) when eating or drinking or expanded gulping during seasons of unnecessary salivation (as might happen when sickened or as the consequence of gastroesophageal reflux illness). The endogenous gases are created either as a side-effect of digesting particular kinds of food, or of fragmented absorption, similar to the case during steatorrhea. Anything that makes food be not completely digested by the stomach or small digestive system may cause flatulence gas when the material shows up in the internal organ, because of leavening by yeast or prokaryotes typically or strangely present in the gastrointestinal tract.

Answer 2

  farts are formed mainly by swallowing air when eating food or drink. They are formed in the large intestine when bacteria ferment carbohydrates, fibers and some types of starches and sugars, which are not digested in the small intestine.
