the mothers womb (uterus)
The substances can pass through the placental wall.
The mothers muscles are pushing him out through the cervix and down the vaginal canal and out through the vaginal opening. Unless there's a c-section where they cut a hole in the mothers belly and take him out that way.
embryo
It is the sack that surrounds the fetus in the womb/uterus. It contains the amniotic fluid and has the umbilical cord passing through it.
The human fetus lives in the mothers uterus, he or she floats in a sack of fluid often called 'the bag of water'.
youre born with it you can poop in your mothers uterus too
No. The fetus is inside the uterus which is closed, like a bag. The rest of the mothers organs are outside the uterus.
The organ where the developing fetus resides is called the uterus. This is where the fetus grows and matures inside the female.
Urine does not pass through the uterus at all...
