It is called chorionic villi sampling.
umbilical arteries
Chorionic villi are of fetal origin and eventually form the placenta
There are 2 type of stem cells * embryonic stem cells * and adult stem cells fetal stem cells are grouped into the adult stem cell category
There are five basic stem cells classifications there is embryonic stem cells, fetal stem cells. There are the Umbilical cord stem cells, placenta stem cells, and lastly there are adult stem cells.
The structure of the placenta is directly related to its function of facilitating nutrient and gas exchange between the mother and fetus. The placenta is composed of villi, which are finger-like projections that increase the surface area for exchange. The villi are surrounded by maternal blood sinuses, allowing for the diffusion of oxygen and nutrients from the mother's blood to the fetal blood, and the removal of waste products from the fetal blood.
It is episitomy
Amneocenteses.
Its a placentation abnormality .Placenta got a fetal site .Fetal site which has a central depression is circumvallate placenta
The placenta is an organ that connects the developing fetus to the uterine wall. The placenta supplies the fetus with oxygen and food, and allows fetal waste to be disposed via the maternal kidneys. The placenta develops from the same sperm and egg cells that form the fetus, and functions as a fetomaternal organ with two components, the fetal part (Chorion frondosum), and the maternal part (Decidua basalis).

Amniocentesis involves taking a sample of the amniotic fluid and checking the fluid for fetal tissue, metabolites, and other markers that would indicate that there is a problem with fetal development. Fetal genetic testing can be performed on the fetal cells in the amniotic fluid. Chorionic villi sampling essentially involves collecting a specific part of the placenta for genetic analysis. Since the placenta is the same genotype as the fetus it is possible to make a genetic diagnosis of the fetus based on analyzing the placenta. Chorionic villi sampling is less invasive and therefore less likely to cause fetal distress.
The chorion.
As in most mammals, the fetal pig will form within the placenta in the uterus of the mother.
