In humans, blastocyst formation begins about 5 days after fertilization when a fluid-filled cavity opens up in the morula, the early embryonic stage of a ball of 16 cells. About seven days after fertilization, the blastocyst undergoes implantation, embedding into the endometrium of the uterine wall.

Which part of the blastocyst contributes to the fetal portion of the placenta?

chorion
The chorionic villi of the chorion extend into the endometrium to form the fetal portion of the placenta. The placenta supplies the growing embryo with oxygen and nutrients; it also removes carbon dioxide and other metabolic wastes.
