It is called chorionic villi sampling.
Chorionic villus sampling (CVS) involves collecting cells from the placenta, while amniocentesis involves collecting cells from the amniotic fluid surrounding the fetus. These tests can be done during pregnancy to obtain fetal cells for genetic testing and detecting chromosomal abnormalities.
The placenta. Deoxygenated blood flows to the placenta where the carbon dioxide is removed and oxygen added. Oxygen rich blood returns to the fetus. Blood is carried to and from the fetus by the umbilical cord.
The umbilical vein carries oxygenated blood from the fetus to the placenta for nutrient and oxygen exchange.
Fetal respiration is the process of exchanging oxygen and carbon dioxide in the developing fetus. It occurs through the placenta, where the fetus receives oxygen from the mother's blood and releases carbon dioxide back into the mother's bloodstream for elimination. Fetal respiration is vital for the growth and development of the fetus during pregnancy.
Oxygenation of fetal blood occurs in the placenta, where the mother's bloodstream and the fetus's bloodstream come into close proximity but do not mix. Oxygen from the mother's blood diffuses into the fetal blood, while carbon dioxide diffuses from the fetal blood into the mother's blood for elimination.
The process you are describing is known as chorionic villus sampling (CVS). It is a prenatal test that involves taking a small tissue sample from the placenta to test for genetic disorders in the fetus.

Yes, during pregnancy, fetal stem cells from the baby can cross the placenta and enter the mother's bloodstream. This phenomenon is known as fetal microchimerism.
In humans, the placenta is primarily formed from the chorion, which is one of the fetal membranes. The chorion develops from trophoblastic cells and interacts with the maternal endometrium to facilitate nutrient and gas exchange. Additionally, the allantois contributes to the formation of the umbilical cord, linking the fetus to the placenta. Together, these membranes support fetal development throughout pregnancy.
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).

In the placenta, oxygen and nutrients from the mother's blood are exchanged for carbon dioxide and waste products from the fetal blood. This process occurs through the placental membranes, allowing for efficient transfer without direct blood mixing. The placenta acts as a vital interface, supporting fetal development by ensuring that the fetus receives the necessary substances for growth while eliminating waste.
Chorionic villus sampling (CVS) involves collecting cells from the placenta, while amniocentesis involves collecting cells from the amniotic fluid surrounding the fetus. These tests can be done during pregnancy to obtain fetal cells for genetic testing and detecting chromosomal abnormalities.
As in most mammals, the fetal pig will form within the placenta in the uterus of the mother.
The chorion develops into the fetal portion of the placenta. It plays a crucial role in nutrient and gas exchange between the mother and the fetus during pregnancy.
