In mammals this is done by the placenta, through which the foetal blood flows and exchanges nutrients/gasses with the mothers blood supply.
The nutrients are absorbed through the placenta by the foetus. The foetus gets the oxygen and nutrition from the mother. The blood of the mother and foetus comes very close to each other in the placenta. Both are not mixed up. They are separated by very thin membrane. The surface area of the contact is very large as compared to the size of placenta.
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.
No - the developing foetus gets its blood supply ONLY from the mother.
a developing fetus receives nourishment from the placenta, which is burrowed into the uterus
The umbilical cord - supplies blood and nutrition to the developing foetus. It's linked into the mother's circulatory system.
pain.
False. The mothers blood flows through the placenta in vessels next to the foetal blood that flows in separate vessels. Oxygen and nutrients can flow from the mothers blood into the foetus' blood and carbon dioxide and waste products can flow from the foetus' blood to the mother's blood through the vessel membranes, however the two bloods will never actually mix.
yes, because the mother will have to breastfeed her child in the process her child will obtain the virus, the virus can not be genetically transferred however
The mother is then pregnant. Its called a foetus.
It can if there is an unusual amount in the mother's environment. Anything that is in the blood of the mother is sent through the foetus, and anything discarded by the foetus is sent through the mother's bloodstream.
The placenta is where the material between mother and child, like nutrients and oxygen, travel from one to another.
