Perivillous fibrin deposition is an abnormal accumulation of fibrin (a protein involved in blood clotting) around the placental villi in the maternal-fetal interface. It is associated with conditions like placental abruption and intrauterine growth restriction, which can lead to pregnancy complications. Excessive fibrin deposition can impair blood flow in the placenta and compromise fetal development.
Placental development allows for proper nutrient and oxygen exchange between the mother and fetus, ensuring the fetus receives essential nutrients for growth and development. It also helps in removing waste products from the fetus, maintaining a healthy environment for fetal growth. Additionally, the placenta produces hormones that support pregnancy and regulate maternal-fetal interactions.
Recurrent miscarriage can be caused by several factors, including fetal, placental, or maternal abnormalities.
It has the same purpose as all other placental pregnancies, it carries nutrients to the fetus from the mother.
No the fetal pig and the mother pig's blood never mix. This is the same with humans and many other placental mammals such as horses and cows.
My guess would be the womb, just like all the other placental mammals.

Embryology
During the 4th month, the first month of the second trimester, the greatest amount of fetal growth occurs.
Compare embryonic growth and fetal development in single and multiple pregnancies, including the incidence of complications and infant mortality.
Fetal cells can be obtained through procedures like amniocentesis or chorionic villus sampling during pregnancy. These tests involve collecting a sample of amniotic fluid or placental tissue, which contains fetal cells that can be used for genetic testing or other analyses.
