What would happen if someone went through the intestines?

[Nyseron]

Specifically alive.
From what I understand the way food is digested involves the stomach acids reducing it to a thick sludge called "chyme".
The chyme travels through the intestines, all the way the liquids and nutrients are sucked out of it.
Finally when the process is over, the only thing left is feces, which is the stuff the body wouldn't absorb.
Vore usually stays true to this idea (with exceptions, obviously) by having the prey perish in the stomach acid and be melted down.
But what if a prey that hadn't been melted down into chyme went through the intestines alive?

Would it have no effect because they aren't a thick sludge or would they have the nutrients sucked out nonetheless, resulting in their own body painfully being converted into feces?

Well it would depend on the prey in question and just how digested they where by the stomach but if we are assuming a strong human prey who has not been even slightly digested then no they would pass through the intestines pretty unharmed.
As the intestines absorb nutrients via expansive absorptive tissue which requires to nutrients to be atleast semi liquid. So in the situation of something solid coming thru does arise it wold go thru fine. we can already see that in the form of sweetcorn sometimes not being digested

Wow!! Not everyday you get a two for one question and answer. The reason you wouldn't digest in the intestines and why there's corn in your poo. Vorephiles are the most scientific of all fetishists.

Lol true, although its mainly from my training in animal and human biology which helps with my understanding x3

[xwrath]

The person would get damaged, intestines have even more digestive enzymes than stomach, and they are the mainly responsible for digestion (the acid is there to create the optimal ph for the enzyme), it's hard to say how damaged tho, but should be at least 3rd degree burns, also the reason why corn isn't digested is humans can't digest cellulose , so if you don't chew properly you'll see it almost intact.

[LuluBoxFox]

yes but for chemical digestion to start it needs some physical for the main part

[xwrath]

The enzymes would still be active, that's why I said it'd be like burns, since physical digestion wouldn't be able to mix the person and enzymes, the would act from outside to inside, with the time the person stays inside, it should be enough for this damage, there would still be a corpse left

Here, let me google that for you...

Here is a delightful video that was made by national geographic on the digestive system about four years ago.
It goes over the basics. I'm sure you can guess at what would happen to a solid non-digested prey if it were in there.

It doesn't contradicts what I've said, the person would get burns, due to the proteases from pancreas intestines themselves, if the greasy coating our skin have was still intact it would be removed by bile, which works like detergent, than proteases would act on skin for the time the person is on small intestines, causing the burns, since human body is solid, this digestives juices would be able to act only over skin.

[Jayezox]

I definitely agree that the person wouldn't be completely intact. When someone gets indigestion, it's not like the food comes out the other end completely intact (or at least not that I heard of). Only materials that completely resist the enzymes like plastic would make it out as if nothing happened (aside from being dirty). Skin and flesh are composed of proteins and stuff which digestive tracts are made to break down. It would just be inefficient in this case so you would be able to tell a human was swallowed when it comes out the other end.

From this site I found a brief overview of chemical digestion: https://www.boundless.com/physiology/textbooks/boundless-anatomy-and-physiology-textbook/digestive-system-23/chemical-digestion-224/chemical-digestion-of-carbohydrates-proteins-lipids-and-nucleic-acids-1104-1171/

To quote this source:

"Protein digestion occurs in the stomach and the duodenum through the action of three main enzymes: pepsin, secreted by the stomach, and trypsin and chymotrypsin, secreted by the pancreas.

During carbohydrate digestion the bonds between glucose molecules are broken by salivary and pancreatic amylase.

The digestion of certain fats begins in the mouth, where short-chain lipids break down into diglycerides because of lingual lipase. The fat present in the small intestine stimulates the release of lipase from the pancreas, and bile from the liver enables the breakdown of fats into fatty acids.

DNA and RNA are broken down into mononucleotides by the nucleases deoxyribonuclease and ribonuclease (DNase and RNase) that are released by the pancreas."


We'll say that the prey is a micro human to keep things simple here. As the prey, the main things to worry about are anything involving the breaking down of proteins. These are a huge part of of the structure (especially the outer structure) of the human body. Carbs and fats, not so much. The purpose of the stomach is more or less to make sure you have a more uniform, sloppy consistency so that all the enzymes and bile and work on you evenly. If you managed to avoid the stomach, I can imagine that you could still take some damage. Your predator would just be missing out on some of the good stuff from your insides.

Right after the stomach is the duodenum, which is the tunnel directly leading to the small intestine. It's where all of the chemicals from your liver, gall bladder, and pancreas squirt their enzymes and chemicals. I'm sure there's going to be some leftover acids from the stomach as well. The chemicals, like bile, that solubilize and break down fats, could definable cause some damage to the membranes of your skin cells if they soaked in enough (think about what prolonged exposure to detergent does to your skin). Then you have to consider the other enzymes that are going to break down your proteins even here after the stomach.

I thin that while it would be much more efficient for your pred to break you down in their stomach, you could certainly be at least partially digested if you skipped straight to the duodenum.

That's definately the best answer. Thanks!

I wonder how tight they would be? A stomach is always assumed to be large (for prey), but intestines would surely be tight to pass through

[hernextmeal]

So are we just ignoring the whole thing where the prey dies due to heat stroke and lack of oxygen?

If the prey passed the stomach alive this is assumed to be ruled out. The question is more about if the intestines would digest the prey even if it passed through the stomach in one piece.

Welcome to the world of vore.

[XDDX]

As far as I know (about how digestion works, not this particular example) nothing (other than death through lack of oxygen) would happen to the prey. The pred might have a digestion problem depending on the size of the prey.

[Emi]

I dislike the idea of the prey getting through intestines ALIVE and here are some reasons why. First and main one: the prey is mostly made of proteins and some fat. Applying some gastroenterology knowledge I'd say that protein digestion requires acid and proteolytic enzyms (pepsin, gastricine, gelatinase, etc. ) which are active in acid only. Intestines mostly have alkaline medium which is good for digesting fats and carbohydrates. Unfortunately this does not mean that intestinal juices will not hurt the prey and the prey will survive. There's no oxygen to breath, but much stinky gases which are unfit for breathing, so the prey will die fast in any case.
This all means that, if meat was not normally digested in the stomach, further it will not be converted into aminoacids, but will just rot. Not a good perspective. So, for those who wants to survive the intestines, you better use special protective suits and oxygen balloons.

By the way, I adore intestines and I love to see the prey remains passing through intestines and slowly turning into feces.

[IvesBentonEaton]

I agree with Emi. I get around the problem with the kwurdāin spell in the setting in which I'm currently writing stories. (See blatant plug below.) Even with heavy protection, an undigested critter is likely to cause a bowel blockage, or at least considerable gastrointestinal distress for the predator.
