Is it fecal matter that passes through mothers stommach directly to the fetus’ intestines. You know.. like a “human centipede” situation, but without any mouth sewed to a butthole.
ALSO: WHERE DOES THE FETUS’ SHIT GO???

You say “fecal matter” as if it is actually poop, rather than the energy rich nutrients needed to grow and survive. It’s not poop, because poop has already been processed and most of it’s useful nutrients have been sucked out.
And for your second question, it goes back across the umbilical cord and is entered into the mother’s waste system.
The fetus doesn’t eat, therefore it doesn’t defecate. The fetus gets nutrients from mom via the arteries in the umbilical cord. The fetus can defecate in the uterus, but this is rare and considered a medical emergency due to risk of aspiration
No, it’s just waste like urea, uric acid, and bilirubin. The fetus doesn’t need to poop for 40ish weeks. Some babies do end up pooping before birth, sometimes because of distress, but also, it’s more likely to happen if babies are late or post term.
Happened to my baby at 41 weeks. she had to be in nicu for 2 weeks because of it.
The umbilical cord has blood vessels that go from the fetus to the placenta and back again. The placenta attaches to the wall of the mother’s uterus, where there is a tangled, intertwined system of blood vessels. The placenta blood vessels lay next to the maternal blood vessels.
So, it’s not poop. In fact the blood vessels on the fetus’ side don’t go to the intestines, they just kinda dump into the bloodstream near the liver. Fetus isn’t eating anything, so no poop.
As the fetal heart beats and fetal blood circulates , it goes out to the placent and back. While at the placenta, where the fetal vessels lie alongside the mother’s blood vessels, they exchange some things. The baby picks up nutrients from the mom, and dumps off waste products into mom’s bloodstream, where they get processed like her own cellular waste, mostly by her kidneys.
That’s a mind-boggling huge amount of misunderstanding right there.

First, nothing about child-bearing has anything to do with a stomach. Fetus’ implant in a womb, or (hopefully not) a Fallopian Tube (this is a medical emergency basically requiring an “abortion”).
Second, oh my God, no, not a “human centipede” situation. The fetus’ mouth is surrounded by amniotic fluid, which, while produced by the mother could never be considered part of the excretory system.
An umbilical cord attaches to the placenta, a specialized organ that resides within the womb, alongside the fetus. The placenta is (hopefully) attached to the interior wall of the womb. Mothers’ *blood* goes into to the placenta and is filtered even more than normal before being passed down the umbilical cord to the fetus. This brings essential nutrients and oxygen to the fetus. The unused nutrients and oxygen are passed back up the umbilical cord with the blood, into the placenta and then back into mother’s bloodstream where they continue the normal circulatory process. Fetus’ don’t poop (except in cases as noted by others), they don’t breathe, they don’t *really* pee (I mean, they kinda do, but not for excretory purposes), they don’t blink. They don’t really do much until *after* they’re born, and a lot of what they do in the first few days after birth is all about learning how to survive without mother’s nutrient processing, waste disposal and respiration. Also, getting rid of tons of stuff they don’t need anymore, because, you know…they’re *born* now (e.g. bilirubin)
