Biologically, what is the difference between vomit and faeces?

Question

Obviously faecal matter has gone further through your system, for want of a better phrase, but what changes take place, and where in the body?

Answer 1

Vomit comes from your stomach, so there's a lot of gastric juices in it. This is basically what you ate plus a whole bunch of acid, the acid is why it kinda burns your throat when you vomit.

By the time it becomes fecal matter, the acid is reabsorbed by your body, also most of the water and nutrients are absorbed in your intestines. So by the time it gets to your butt, all of it is undigested food, wastes secreted by the liver, and waste from bacteria lining your large intestines.

Answer 2

Vomit is partially digested food, and it contains bile from the gall bladder. And also acid from the stomach.

Faeces is mostly fibre, most of the goodness has been taken out of the food in the intestines, so its left as bare fibre, but there is also small amounts of good elements as the process of taking away those good elements isn't effective enough to totally remove them altogether.

Your stomach uses enzymes to break down all of the food, then it passes onto your intestines, in here the useful parts in the food is taken out most likely via diffusion, or in some cases transport proteins in the epithelial layer lining the intestines. Faeces is left after it has passed successfully through the intestines, just the bare elements in the food that we did not want. But the main body of faeces is very useful, without it, peristalsis would not be very effective.

Peristalsis is the squeezing of muscles of the intestines, which makes faecal matter move forward pushing that ahead of it also. Moving it by mass flow.

Answer 3

Vomit is actually the contents of the stomach and contains un/semi-digested food, liquids and stomach acid. Faeces on the other hand fully processed waste matter which has passed through the small and large bowel, which has had most of the liquids removed (which are filtered through the kidneys and end up as urine) and contains the undigestable material from the stomach with other bodily waste matter (like old used bood cells that have been processed/scavenged - which accounts for the brownish coloration)

Answer 4

When you eat, food goes into the stomach where it is mixed with stomach acid, churned and turned into mush. From there it travels into the small intestine and goes on a lovely journey were all the nutrients are absorbed before it goes all the way out, the other end with just the 'mass' left. Vomit still has the nutrients in it that would be absorbed in the small intestine where as faeces has had all the nutrients absorbed.

Answer 5

Vomitting is done by the stomach to expel food which is irritating in some way. Faeces is the food which has been digested and from which the nutrition has been absorbed by the intestines.

So, vomit is undigested food and faeces is the waste product of digestion.

Answer 6

Basically, vomit,also known as vomitus, is actually food that has been half-digetsed by the hydrochloric acid secreted by your stomach. In layman terms, this acid is know as the gastric juice. So when you are being flipped around abit,your stomach starts to get queasy and the contents start to 'roller-coaster' about in ur tummy.and then it causes a reflux into your oesophagus known as oesophageal reflux, which results in it coming out through your mouth.

ok...for faeces..they get digested in ur stomach then go on to your small intestine where they stay for twelve to fourteen hours. Then they get passed to the large intestine, which consists of ascending colon, transverse colon, descending colon, sigmoid colon and then to your rectum. The rectum is where your faeces are stored until it is time for removal through your anus.

That's the difference between vomit and faeces. :)

Answer 7

Vomit is undigested food that has not been in the stomach long enough. Faeces is undidested matter that is left after the useful protein, carbohydrate,fats and water with dissolved minerals has been absorbed. This happens in the small intestine (prots,carbs & fats) and large intestine(water and minerals).

Answer 8

Faecal matter has been digested - it's passed through the stomach, and mixed with the various enzymes in the gut, which break it down. Vomit has not yet reached the stomach, and has only had one enzyme (er - dunno the name) to star the digestion process, but the process did not complete

Answer 9

Bile is produced by utilising your liver and could be yellow-greenish in coloration and skinny. Vomit on the different hand is heavier and its coloration would be based on the fabric you're expelling on the time. Sorry if this is TMI.

Answer 10

vomit is undigested food, which your stomach rejects , faeces is digested food , your body has taken out all the vitamins and minerals, and rejected the things your body doen't need
