| chorionic villi |
the bulk of the placental disc is composed of chorionic villi. The villi reflect progressive extension of the chorionic villous tree, beginning with main fetal stems branching off the chorionic plate early in pregnancy. Branching and formation of new chorionic villi continues in many placentas until term, and fetal nutrient exchange occurs at their interface with the intervillous space

This procedure tests for genetic fetal defects by analyzing a piece of chorion, which is the outer tissues of the sac surrounding the embryo. CVS can be done earlier than amniocentesis, typically between 9 and 11 weeks of pregnancy.

| chorionic villus sampling |
A fetal monitoring technique in which a sample of chorionic villus is extracted through the cervix or abdomen. The sample is tested for chromosomal or biochemical abnormalities. Chorionic villi are the short folds of the outer membrane surrounding the fetus from which the placenta is formed.
