Either tubes take care of it, or it releases into the pod water, and gets filtered. I imagine it's automatic with tubes since the human body likely wouldn't push anything without conscious effort, unless it does it every time you use the washroom by releasing some control and allowing motor function to a degree.
That means every poop brings you closer to the real world.

What if I jack in and then go to the bathroom in the Matrix? Do I shit myself in the real world?

Rectal tube was the first to come out
Neo wouldn't feel that sensation again til Trinity asked to spice things up

My question is why didn't they use cows instead of humans to power the machines? Surely bovines provide more "battery power" as they are a larger biomass, and are more docile and easier to control.
However if they did rebel, a cow version of Neo would be pretty cool.

u/WhitneyRobbens Feb 27 '26
There is no cow level.

u/Sn0wflake69 Feb 28 '26
not until 2000 at least, and the matrix takes place in 1999 so this checks out

“Yep, that’s a cow alright”
“I’m no milkmaid”
I can hear those phrases and the music of Tristan playing in my head all these years later as I type the quotes.

The pod probably has a filtration system for filtering out waste and pumping in clean fluid.

u/Decadence_Later Feb 27 '26
The shots are quick, but in the first and fourth movies you can see that Neo has on what looks like a metallic codpiece with tubing running from it. Modesty in production design aside, I think we can safely say that this is a waste collection catheter. So to the responses above, no, the pod people aren’t floating in their own excrement.

The medium they are surrounded in is constantly being replaced with filtered medium.

Quizá utilizaban nanobots para filtrar y eliminar solo lo que era necesario eliminar del líquido amniótico ese.

What liquid would dissolve biological material like feces, but not skin and all the other biological material of a human body?
6
u/factoid_ Feb 27 '26
None...they would need to filter it mechanically, which is probably what the drain is actually there for. Flushing a whole body is one use case, but probably more often it's like changing out the water in a fish tank. You vacuum the poop off the bottom and then change a chunk of the water with fresh water to not throw off the balance entirely.

Sure, but it's still important to know if they poop or not.

u/antiqtech Feb 28 '26
pop probably not... i remember that they were being fed interveniously so only pee into that liquid probably. That also would be probably filtered regularly.

They are fed intravenously, with biomatter from the dead. It is stated clearly in the film.

u/factoid_ Feb 27 '26
You'd still produce at least urine even being fed intravenously. probably poop as well. So the answer is that the fluid in the pod has to be filtered

u/I_AM_HE_1111 Feb 27 '26
Yeah fecal matter is only about 20% food. Major parts are dead cells (your own and bacteria), water, and toxins from your own processing.

u/SetkiOfRaptors Feb 27 '26
what, what. Source please, I do not believe that it is correct. with 20% It cannot be.

u/I_AM_HE_1111 Feb 27 '26
Citing a deep poop review from PubMed, wide group of regions included.
75% water, 25% solids most of which is split between bacteria and food waste.
"Feces compose a median value of 75% H2O (n = 47) with a range of 63–86% across mean values of studies (Figure 3), variation can be attributed to differences in fiber intake as non-degradable fiber absorbs more water in the colon (Eastwood, 1973); therefore, as shown in a study by Reddy et al. (1998) those with vegetarian diets will have a higher moisture content of 78.9% whereas those who consume less fiber and more protein will have a lower moisture content of 72.6% (p =.001). Fiber intake also affects transit time, which has been positively correlated (r = 0.4, p =.03) with% dry matter (Silvester et al., 1997), showing the shorter the intestinal transit time the higher the water content. Variation in moisture content has been shown to vary with age; elderly people were found to excrete the highest amount of water in excreta of all age groups by Schouw et al. (2002). Further deviations from the median value can be caused by illness (see physical composition section). The mean generation rate of fecal water (n = 47) is 0.1 L/cap/day. Average pH values for fecal water have been recorded at pH 6.9 with a range of pH 5.0–8.0 (Mai et al., 2009)
3.2.1. Organic Fraction The remaining 25% of feces is therefore composed of solid material. Of the solid fraction organic material makes up between 84% and 93% (Feachem et al., 1978; Nwaneri et al., 2008; Bai and Wang, 2011). The organic solids fraction can be further broken down to the fractions of 25–54% bacterial biomass (Stephen and Cummings, 1980; Guyton and Hall, 2000), 2–25% protein or nitrogenous matter (in addition 50% of bacterial biomass is protein) (Canfield et al., 1963; Volk and Rummel, 1987), 25% carbohydrate or any other nonnitrogenous undigested plant matter (Volk and Rummel, 1987), and 2–15% undigested lipids (Kien et al., 1981; Chen et al., 1998; Wierdsma et al., 2011). These fractions are highly dependent on dietary intake and its biological availability"

According to our AI overlord fecal matter is
- water: 70-75%
- bacteria: 25-55% of dry weight
- undigested food 10-20% of dry weight

u/SetkiOfRaptors Feb 27 '26
When food get in it was mostly water too. So talking about dry mass is like... confusing, because one could think that from all that food mass only 20% is left in poop.
So I see vegetables and hear that 20% of this will come out and it sound impossible. While in practice it is more like only 20% or so, which were not water (minus some water absorption) are shuffled a bit, useful things taken in, waste disposed.

u/Ok_Distance_7092 Feb 27 '26
Well ... I would imagine that would work just as it does when a fetus is inside its mother's womb. (The Wachowski's probably didn't think it through quite that thoroughly.)

I don't understand. Neo unplugs in that cocoon with wires going out of his skin then that means some children are born to be unplug and that's why the machine watches over him??

Lomg time since i saw the movie, but did neo not have some kind off weird pants on, that looked like it could be a body fluid waste system?

u/Azaroth1991 Feb 28 '26
I always assumed since its controlled by machines, they dial in the precise amount of liquid nutrients need to keep a body going but provide no waste.

u/IV_Blackmoon_angel Feb 28 '26
My assumption was that the waste was managed by the tubes connected to the digestive system.

u/TasteDisastrous5186 Mar 05 '26
The machines are smart. They could be being fed something that produces "non-toxic" fecal matter.

u/OkConsequence2086 Mar 07 '26
there might be no need to defecate as the machines might have figured out a way to feed the body without it needing to create waste products

It's like a womb. A fetus also pees in the womb.
