A mammalian embryo gets oxygen and nutrients from it mother by means of the umbilical cord which extends the embryonic blood supply into the placenta embedded in the mothers womb. The blood supply in the placenta is close to that of the mother and oxygen and nutrients diffuse across from the mother to the baby. With egg laying animals the nutrients are supply to the embryo as the yolk part of the egg and oxygen is supplied by diffusion through the permeable shell and shell membrane
The Placenta uses a the process of diffusion to diffuse the nutrients from the mothers blood into the babies. Then the umbilical cord carries the nutrients to the baby to the Placenta. Answer is Placenta
Oxygen and nutrients.
blood
Instead of getting oxygen and nutrients directly from a mother, the bird egg contains these elements in the materials found around the bird embryo. Reptiles and amphibians have similar processes for supplying the embryo.
Through the placenta, via the umbilical cord.
Umbilical cord!!
umblical cord
The embryo is connected to the umbilical cord to the mother. The baby feeds on what its mother eats. Absorbs the nutrients and oxygen it needs. Drugs and other harmful substances will affect the embryo's development and it could possibly cause low birth weight, early birth. Also it will cause the embryo now a fetus have problems receiving oxygen and nutrients from its mother.
food
True
The Placenta.
