Eli5: When a baby is in the womb, where does the waste go?
In: Biology
A babies digestion system does not start working before they are fed. So there is no poop while the baby is in the womb. As for the pee it is a bit different. For most of the baby’s development the kidneys will not work so there will be no pee. Instead the blood will be pumped through the umbilical cord where any waste products gets filtered into the mothers blood and out through her kidneys and urine. Even after the kidneys of the baby starts working this system will filter out most of the waste from the baby’s blood. And the little urine there is will be absorbed by the walls of the womb.
