How does fart travel

All of these gases in the digestive system have to escape somehow, so they come out as farts! Gases are also what can make farts smell bad. Tiny amounts of hydrogen, carbon dioxide, and methane combine with hydrogen sulfide say: SUHL-fyde and ammonia say: uh-MOW-nyuh in the large intestine to give gas its smell. All people fart sometimes, whether they live in France, the Fiji islands, or Fresno, California! If you have a dog, you may have even been unlucky enough to have heard or smelled Fido farting.

But it is most known as farting. And, while we are still small children, we develop a fascination with one of our body's most basic functions — the accumulation and expelling of gas through the rectum, known as flatulence. If we didn't pass gas, we would explode," says Dr. Our bodies have two processes to remove gas: belching or burping and flatulence. Belching is mostly caused by the air we swallow, and it releases gas from the upper GI tract — the stomach and the esophagus.

Flatulence occurs in the lower gastrointestinal GI tract. Most gas passed during flatulence goes unnoticed because there isn't a smell. It may contain odorless gases, such as nitrogen, oxygen, hydrogen, carbon dioxide and methane, but a small portion includes hydrogen sulfide, which causes it smell like rotten eggs.

Think of hydrogen sulfide as the waste of the microbes helping you digest the indigestible. Then, there are other factors contributing to smelly farts, including compounds that are byproducts from meat digested, and whether there is feces present in the rectum when flatulence occurs. FODMAPs fermentable oligosaccharides, disaccharides and monosaccharides, and polyols are the types of carbohydrates that can create digestive issues, such as gas, abdominal pain, bloating, constipation and diarrhea.

Conditions that create excess flatulence do so through various mechanisms. Some farts are caused by swallowing air while eating or drinking, while others are produced by foods such as beans, dairy products, onions, garlic, broccoli and cabbage. This video from YouTube channel AsapScience explains the science behind what happens when humans pass gas and if it's possible to outrun the embarrassing sound of a fart you can't or more importantly, the smell.

Because we all have a unique set of scent receptors, we all perceive smells differently. So when we cut the cheese, the scent will be different to our noses than to someone else's. Plus, the composition of each fart is distinct depending on what you ate, your food bacteria and the air you swallowed when you ingested your food.

According to the video, the average fart is composed of 59 percent nitrogen, 21 percent hydrogen, 9 percent carbon dioxide, 7 percent methane, 3 percent oxygen and 1 percent of the actual part that smells.

Everybody farts. We fart at home, we fart at work, when we know it's a stinker, we fart with a smirk that rhymed! But how much do you really know about those mysterious smelly toots of yours? What IS a fart? We've got answers.
