You liked this question so much you asked it twice. And it's still as stupid the second time!!~:()=

The author of the question does not mean breathing as passing of gas, but flatus, to use its medical name, or to use the vulgar English term, farting.\n\nThe 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).\n\nNitrogen 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.\n\nI've lasted a good ten seconds letting one rip. Having had appendix problems for nine months (a long story, useless health system in the UK, etc.), I found that during that period, my flatus was more stinky than normal. Having had my appendix removed, it returned to normal in terms of odour.\n\nI find that drinking beer tends to produce the worst smelling flatus about twenty hours later.

A quief is very different from a fart in amny ways. A fart is something you can use your muscles to make it quieter or no come at all. A queif, you can neither make it quieter or not come out at all. A fart is something that can smell bad because it really is fecal molecules coming out. A quief is not smelly and is nothing more than air.\n\nA quief is caused by air being forced into the vagina and then forced back out. This happens more frequently during sex, but can happen during certain exercises and other activites. Though it may be embarrassing, it really shouldn't be anymore embarrassing than a hiccup. You can't prevent hiccups, you can't quiet them, and you had nothing to do with getting them in the first place. That is basically what a quief is.\n\n\nPutting your legs above your head increases the liklihood of quieffing, so if you are trying to prevent it, this may be your only way.\n\nDoes that help?

Gas is caused by bacteria called methanogens that live in our digestive tracks. They are helpful bacteria that break down food. One popular one is E. coli. It lives in our intestines and is not dangerous, but if eaten it causes food poisoning. This can happen when disgusting people dont wash there hands after using the restroom.

when a womans vagina "farts" while having sex its called qweefing, i could be spelling it wrong, but it is caused from too much air being pushed up in her vagina by the penis and when the penis is out the air is then released! you will notice qweefing more depending on the position.....most women qweef a LOT after they are done with doggy style position ALSO if you have sex and then switch to doggy style most women qweef when they put their butt in the air because the excess air is being released!! but qweefing is just a sound it does not have a smell!

I believe it is grammar, but close enough buddy. I know that the a-key is close to the e-key. I make that mistake to!\n\nMy wife never farts either. Not even when she eats beans. My sister-n-law however passes gas like a maniac. Louder bombs than mine, funny ? bro.

easy\n\nchemical process, when we process foods we divide the food with the stomach acids, this creates a chemical efect that relises butane and other gases in your intestine, when you fart, you can truly light up your fart and it will burst..\n\nlol but dont do it with out underwear or you will have bad experiences :(

Its when theres an air pocket and we rub it and we push that air pocket...so it makes a farting noise.\n\nIt happened to my ex a few times long time ago, but I knew it was normal so it didnt phase me.\n\nAll men know its a normal thing, so dont wig out...its a beautiful thang.

Woooooooo hoooooooooo hooooooooo\nU tried something new baby.\nI don know how I like it but may b water vapour molecules that get stuck up with the fart molecules make the smell more denser and more grossy.........\nI m outa here or ur fart may come up any time now......\n\n\nPPPPPHHHHHHHHHwwwwwwwwtttttttttttttttttt.................................

A fart is the cry of an imprisoned turd.  I'm not sure if the actual fart knows where it came from, but the turd apparently does, if it's screaming to get out.

When a woman "queefs" she is NOT expelling gas from her vagina. It is impossible to expel gas from that opening because it does not connect to the small intestine.\n\nA "queef" is simply air (just air like the air you breathe) that gets trapped in the vaginal canal. Air can get trapped in the canal during rigorous sex or if the woman works her kegel muscles (the muscles lining the vaginal canal) and moves air into the vagina by accident.\n\nIt is natural function and no woman should be embarassed if she "queefs" during sex.

the question is why do you smell your dogs butt?

Because the water funnels the sulfur dioxide (or whatever gasses cause the SMELL) right to your nose, instead of letting the gasses diffuse through the air, like when you fart OUT of the tub.

This happens to me sometimes.. it could be the sign of a high-fiber diet and your body's struggling to metabolize food at the rate at which you're using energy.  Digestion of food produces waste gases.  For example, yesterday I got on my bicycle and rode almost 60 miles.. halfway during the exercise, the farting started, and now today it's still happening.. my body may not have yet caught up with refueling the 3000 calories I burned.\nThe excrement might be caused by what you're eating.  High fiber sometimes makes for loose stools.  It wouldn't be uncommon for a little of it to come out when passing gas.\n\nHope none of you were eating dinner when I answered this.  Ha!

Think of where it is coming from... \n\nThat HOLE isn't exactly the most beautiful place and (I don't know about you - but for me -  I don't particularly like to invision breathing the fumes that come out of that orifice)\n\nI think for many people it is similar - just hearing a fart makes them think - "Eww I am breathing the fumes that came out of someone elses butt!"  It's just gross.  \n\nSo yes - even though "smelly" ones are worse, the non-stinky variety are still YUCK because they are there.  We are forced to hear and then breath that air around you after KNOWING that you just farted.  :p

Farts are not a single molecule.  In fact, they are primarily aerosolized feces.  The smaller molecules that are a byproduct of digestion often become gaseous in the intestinal tract and are expelled as farts.\n\nThere are far too many possible compounds in farts to list them, but a popular one to talk about is methane.  Only 1/5th (or so?) of humans produce methane in their farts, a flammable molecule that doesn't smell particularly good.\n\nhere is a page with a similar but more detailed answer:\nhttp://www.heptune.com/farts.html

They smell, even, before they pop. You would have to intercept them to find this out. . . . and, indeed, they do smell even after they pop (or is it poop?). \n\nThe only thing the water does is cool them down a bit. The temperature of a fart at inception is 98.6 degrees and maybe let a little diffuse into the water (but not much).\n\nAn interesting little fact is that when you detect odors you are actually getting a tiny bit of whatever you are smelling in your nose (hmmm?).\n\nGotta let this go now.
