Question

__________ is a procedure in which a small piece of membrane is removed from the chorion, a layer of tissue that develops into the placenta.

Answer 1

Chorionic villi sampling (CVS)

Step-by-step explanation:

Chorion is one of the extraembryonic layers. One of the functions of the chorion is the formation of the placenta in humans. Chorionic villi sampling (CVS) is one of the procedures for genetic testing. During CVS, a tissue sample from the chorionic villi is collected by placing a catheter in the uterus or inserting a needle through the abdominal cavity. The chorion cells and fetal cells are genetically identical. Therefore, these tissues are analyzed to identify possible genetic disorders.
