Yes. Anything in the mother's blood goes through.
No. Tylenol 3 has acetaminophen(Typenol), codeine & caffeine. That is all. Oh, and some fillers & binders that when crushed up, diluted & injected into a vein, travel to your lungs & destroy them (sort of like asbestos, but different - it's called chalk lung or talc lung). Fun, huh
Through the placenta via the umbilical cord to the foetus.
Through the mother's lungs into her bloodstream, then across the placenta and through the umbilical cord to the fetus.
Only if there is a tear however small. Sometimes this can happen at birth.
The young of placental mammals develop within a placenta. The placenta is a thick membrane that is connected to the inside of the uterine wall. The umbilical cord connects the baby to the inside wall of the placenta. Nutrients and oxygen go from the mother's blood stream through the placenta, down the umbilical cord, and into the baby. The baby releases waste products and carbon dioxide, which travel up the umbilical cord, through the placenta and into the mother's blood stream.
Sperm does not travel to the placenta; rather, it fertilizes an egg in the fallopian tube. Once fertilization occurs, the resulting zygote travels to the uterus, where it implants itself into the uterine lining, not the placenta. The placenta develops later as the embryo grows, facilitating nutrient and waste exchange between the mother and the developing fetus.
The mammal embryo receives its nutrients from the mother through the placenta. The placenta allows nutrients to travel from the mother's system to the embryo's, and for waste products to leave the embryo's system so they can be disposed of by the mothers.
They are transported from the placenta through the umbilical cord to the fetus. The baby takes nutrients and oxygen from the mother's blood, which travel's through the umbilical cord to the baby
Travel is not recommended.
first you have to consult your doctor the only you can travel
In the placenta, oxygen and nutrients from the mother's bloodstream diffuse into the fetal blood through the chorionic villi. The umbilical cord then transports this oxygen-rich blood to the fetus. Conversely, carbon dioxide and waste products from the fetal blood travel back through the umbilical cord to the placenta, where they enter the maternal circulation for elimination. This exchange occurs without direct blood mixing between mother and fetus, ensuring efficient nutrient and gas transfer.
No, it is generally not permissible nor advisable to travel by air when you have placenta previa. There is a risk of life-threatening hemorrhage with the condition and this cannot be handled adequately in a plane. When you have the condition, your doctor will usually want you to be in hospital for the remainder of the pregnancy, or within easy reach of one. Obviously, this excludes air travel.
