What are the extra-embryonic membranes that surround a fetus?
The extra-embryonic membranes that surround a fetus include the amnion, chorion, allantois, and yolk sac. The amnion forms a protective sac filled with amniotic fluid, providing cushioning. The chorion contributes to the formation of the placenta and facilitates nutrient exchange. The allantois is involved in waste management and gas exchange, while the yolk sac provides early nourishment before placental circulation is established.
How many sacs surround a fetus?
1
How do perinatal transmissions infect the fetus?
Perinatal transmissions infect the fetus after its protective membranes rupture--the waters break--and during labor and delivery when the fetus is exposed to maternal blood.
What are amniotic membranes?
A thin membrane surrounding the fetus and containing serous fluid.
Where do the amniotic membranes come from?
The amniotic membranes are formed from the fetal tissues, specifically from the fetus's skin and cells lining the amniotic cavity. These membranes start developing early in pregnancy and play a crucial role in protecting and supporting the developing fetus in the womb.
What two body parts surround and protect the fetus as it develops?
uterus and the amniotic sac
Does the diaphram function in the fetus?
No
What are the complications that may follow premature rupture of membranes?
Premature labor and delivery of the fetus, infections of the mother and/or the fetus (amnionitis and endometritis), and compression of the umbilical cord (leading to oxygen deprivation in the fetus).
What happens if the membranes have already ruptured in premature labor?
If the membranes have already ruptured, it may be difficult to stop premature labor. If infection of the membranes that cover the fetus (chorioamnionitis) develops, the baby must be delivered.
