The chorionic membrane is the outer sac which surrounds the developing fetus
The three types of villi are: Intestinal villi-microscopic finger like projections on the inner surface of the ileum. Chorionic villi-villi on the outermost membrane of the foetus. Arachnoid villi-villi on the arachnoid membrane of the brain.
Human chorionic gonadotropin (hCG) is the hormone secreted by the developing embryo after implantation in the uterus. It is detected in the blood and urine and is commonly used as a marker for pregnancy testing.
Chorionic villi develop into the placenta, an organ that provides oxygen and nutrients to the developing fetus and removes waste products. The placenta also plays a crucial role in hormone production to support pregnancy.
The chorionic villi, which are finger-like projections on the surface of the chorion (part of the fetal membrane), contain blood vessels that allow for the exchange of nutrients and waste between the mother and the fetus.
The process you are referring to is called chorionic villus sampling (CVS). It involves using a long thin tube to obtain a small sample of cells from the chorionic villi on the fetal side of the placenta for genetic testing.

It is also known as Chorionic villus sampling
It is also known as chorionic villus biopsy
Chorionic villus biopsy has been in use since the 1980s
Chorionic villus sampling has been in use since the 1980s
Placenta produces Human chorionic gonadotropin hormone.It is tested for pregnancy.
A chorionic villi sampling can be performed as early as week 10 of the pregnancy.
Chorionic villus sampling is best performed between 10 and 12 weeks of pregnancy
Chorionic villus biopsy is not recommended for women who have vaginal bleeding or spotting during the pregnancy
Chorionic villus sampling is not recommended for women who have vaginal bleeding or spotting during the pregnancy
Chorionic villus sampling involves the removal of a small amount of tissue directly from the chorionic villi (minute vascular projections of the fetal chorion that combine with maternal uterine tissue to form the placenta).
Chorionic villus biopsy costs between $1,200 and $1,800. Insurance coverage for this test may vary
