What else can I help you with?
What way does blood normally pass across the placenta?
blood does not pass across the placenta
Can HIV travel from mother's blood to fetus through placenta?
Only if there is a tear however small. Sometimes this can happen at birth.
What would happen if the placenta was damage?
Placenta gets damaged by toxins like alcohol or chemicals from cigarettes. This leads to prevention of blood from mixing and/or an affected child by transportation of toxins from mother to child.
Blood through the umbilical cord to the placenta?
Yes your blood supply is shared with your baby though the placenta.
Where does the exchange of respiratory gases take place between a mother's blood and the blood of her fetus?
Placenta
Does the placenta have a good blood supply?
False- The placenta supplies the baby with the mother's blood during development.
What structure carries blood between the fetus and the placenta?
The umbilical cord carries blood between the fetus and the placenta. It contains two arteries and one vein that transport oxygen and nutrients to the fetus and remove waste products.
What carries fetal blood to the placenta?
The umbilical vein carries oxygenated blood from the fetus to the placenta for nutrient and oxygen exchange.
How nutrients oxygen and waste are exchanged between the fetus and the mother?
Nutrients, oxygen, and waste are exchanged between the fetus and the mother through the placenta, a temporary organ that develops during pregnancy. The mother's blood containing nutrients and oxygen passes through the placenta, where it comes into close contact with the fetal blood vessels. Through diffusion and active transport processes, nutrients and oxygen are transferred from the mother's blood to the fetal blood, while waste products such as carbon dioxide are transferred from the fetal blood to the mother's blood for elimination.
A membrane rich in blood vessels?
Placenta
How does the fetal circulation work?
The blood goes from the mother to the placenta where gas exchange occurs to the fetus. From the placenta the blood goes into the arterium and to the body of the fetus.
When does babys blood mix with the moms during birth?
During birth, the baby's blood can mix with the mother's blood primarily during the placental separation phase, when the placenta detaches from the uterine wall. This typically occurs after the baby is delivered but before the placenta is expelled. While the circulatory systems are separate during pregnancy, small amounts of fetal blood can enter the maternal bloodstream, particularly during labor and delivery. This mixing can also happen if there are any tears or breaks in the placenta or umbilical cord.
