pain.
Through their genes - or during pregnancy ! Many diseases can (and usually are) passed down from the mother to the foetus through the umbilical cord.
that would be the oxygen because whene a foetus breaths out it cant breath anywhere so it gouse to the mother and she exhales it out
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 foetus in embedded in fluid called amniotic fluid. Some times the foetus takes a breath in that fluid, just before the delivery. The result is disastrous. If the foetus is born with the fluid in the lungs, it is going to die in most of the cases. The foetus is getting all the oxygen and the nutrition from the mother. This is supplied through the placenta. So the lungs of the foetus are at rest in the womb of the mother.
Ellicit drugs, alcohol and nicotine.
Everything is supplied and filtered by the placenta.
HIV infection lies in DNA of the nucleus of the cell. Normally no cells pass from mother to fetus. There is layer of placenta to prevent this. But this barrier is broken during the delivery. There is mixing of blood from the mother and fetus. So your doctor will like to go for Caesarean section delivery in such case. She will give some drugs also to prevent the risk of HIV transmission.HIV does not pass from mother to foetus during the pregnancy. Blood of mother and foetus is not get mixed in such cases. It can pass during the normal delivery, when the mother's blood can get mixed with the blood of foetus. That is why the delivery by operation is indicated in such cases. Your doctor will give you some medication to minimize the risk.
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.
it's the emberyo because its the blood from the baby is used for the mother so it is very good for a mother to use !
A growing foetus needs the cord because it gives the food and oxygen from the mother into the babyThe cord feeds the baby and gives the baby oxygen.All foetus's need a cord !
