The placenta.
For the same reason that girls do. When babies are in the mother's womb the umbilical cord is connected to the baby's belly button to give it nourishment.
No. The womb is your uterus. The placenta is what attaches the baby to the umbilical chord and provides the baby with nutrients. During labor the female will expel the placenta after the baby is delivered.
The fluid surrounding the baby in the womb is called amniotic fluid. It provides protection and cushioning to the developing baby.
Yolk Sacks provide nourishment until they can get food for themselves.
A fetus does have amniotic fluid in the mouth, and the lungs. It enters through the nostrils. There is no air in the womb, the baby is surrounded only by amniotic fluid. The baby, once born, has to cough (or cry) out the amniotic fluid before it can breathe the air.
The fetus inside of a mother's womb receives nourishment via the umbilical cord from the food the mother ingests.
Without nourishment, the baby will not develop properly.
semen does not cross into the placenta and has no effect on baby in womb.
hysterectomy is removal of womb which is where baby grows. No womb = no baby
baby poop while in the womb can cause infection in the lungs if the baby swallows it
Amniotic fluid keeps the foetus warm while in the womb, provides lubrication for the baby, and allows the baby move about to strengthen their bones before they are born.
