The chorionic villi of the placenta are responsible for the exchange of material between the mother and fetus. The chorionic villi are finger-like projections that extend from the chorion (the outermost fetal membrane) and embed themselves in the mother's uterine lining. This allows for the exchange of oxygen, nutrients, and waste products between the maternal blood and fetal blood.
