Step-by-step solution

The trophoblast layer gets attached to the endometrium and the inner cell mass gets differentiated as the embryo. The blastocyst becomes embedded in the endometrium of the uterus called implantation which leads to Pregnancy. After implantation, finger-like projections appear on the trophoblast called chorionic villi which are surrounded by the uterine tissue and maternal blood. The placenta facilitate the supply of oxygen and nutrients to the embryo and also removal of carbon dioxide and excretory materials produce
