The placenta.
the placenta, it gets expelled out after the baby is born.
Placenta previa, placenta accreta, placenta increta, and placenta increta are all conditions stemming from abnormal implantation of the placenta.
Placenta is a circular organ connected to the uterus in the women which helps to nourish the feutus through umbical cord.
Placenta Previa is when the placenta forms in the lower part of the uterus, covering all or part of the opening to the cervix. It is not usually a problem during early pregnancy, but can cause problems later. Later in pregnancy, it can cause bleeding, which may require you to deliver early. Women with Placenta Previa are required to deliver through cesarean section. http://www.babycenter.com/0_placenta-previa_830.bc
No - the placenta grows around the fetus in the uterus as part of the pregnancy. The ovaries just supply hormones and the egg that gets fertilized.
Yes, in fact if she does so it helps the uterus contract, decreasing bleeding and helping to get the placenta out faster.
This condition is called Placenta Previa. With placenta previa, the placenta grows on the lower part of the uterus partially or totally covering the opening of the cervix. The placenta should form at the top of the uterus, above the baby. With a normal pregnancy, the baby would be born first, then the placenta. With placenta previa, the placenta would be delivered first. Women with placenta previa require a c-section because as soon as the umbilical cord comes into contact with oxygen, the baby will automatically breathe with his lungs. Delivering the placenta first puts the baby at risk of suffocation in the womb.
The fetus receives oxygen and nourishment from the placenta via the umbilical cord. Waste and carbon dioxide return to the placenta via the umbilical cord.
I hope so.
A tether in women typically refers to an umbilical cord that connects the fetus to the mother's placenta, providing nourishment and oxygen during pregnancy.
