a developing fetus receives nourishment from the placenta, which is burrowed into the uterus
blood
It comes from a temporary organ called the placenta. The fetus is connected to the placenta by the umbilical cord. From the placenta, which is normally attached to the uterine wall, blood, oxygen, and nutrients are transferred through the umbilical cord to the developing fetus.
The placenta is where the material between mother and child, like nutrients and oxygen, travel from one to another.
the wall of the uterus where oxygen, nutrients, and waste exchange takes place between the mother and fetus
Baby gets food and oxygen through the umbilical cord. This umbilical cord is attached to the placenta. This placenta is attached to the uterus. In the placenta blood of the mother comes close to the blood of the fetus. There is transfer of food and oxygen to the blood of fetus from the blood of mother. Carbon bi oxide and waste products of metabolism are transferred to the blood of mother from the blood of fetus.
umbilical cord
they do
first
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
how nutrients,oxygen and waste are exchange between the fetus and the mother
The umbilical cord connects the baby to the placenta which attached to the mothers utuers. It provides oxygen, blood and nutrients to the developing baby via the mother.
