Weakness, dizziness and loss of consciousness for the mother, intrauterine growth restriction and brain damage do to low oxygen levels for the baby. Keeping your iron (RBC) level normal during pregnancy is very important for fetal health.
Yes they are always harmful. It enters your blood stream and effect your blood cells.
A baby and its mother use different bloods. However, the placenta, that allows nutrients to pass into the baby, can also allow harmful substances.
From oxiginated blood from the mother.
trough the placentai thinkshould be umbilical cord...... I think too
The substances can pass through the placental wall.
placenta
No, the baby is supplied with food in its blood via the placenta, the placenta is connected to the mother's blood supply and the baby's food gets to it from the mothers blood.
The mother's blood supply enters the foetus via the umbillical cord and allows oxygen to diffuse from the mother's blood into the foetus.

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.
Cigarettes are harmful to the development of a fetus, because they create a degree of carbon monoxide poisoning in the mother, which reduces available oxygen to both mother and fetus, and because nicotine is also a vaso-constrictor, making blood vessels contract, thereby reducing blood flow to the fetus.
The parents of a husband are not related to the parents of his wife. Answer There is no relationship at all as there is no blood tie with either of the mothers. If however the mother in law was the mothers sister, then that would be the relationship i.e. sister.
