Which blastocyst structure becomes the chorion and cooperates with uterine tissues to perform the placenta?

What two tissues does placenta form?
trophoblasts/chorionic villi and the uterus form the placenta
What are two associated structures in the placenta?
umbilical cord and fetus
What is the name for the protective structures that form around an embryo?
Placenta.
What structures form the placenta?
Chorionic villi & Decidua Basalis
What structures ultimately forms the placenta?

What are the two structures that produce human chorionic gonadotropin?
placenta and germ cell
What three structures protect and nourish the developing embryo?

What two processes are happening in blastulation?
In mammals, the blastula forms the blastocyst in the next stage of embryonic development. Here the cells in the blastula arrange themselves in two layers: the inner cell mass and an outer layer called the trophoblast . The inner cell mass is also known as the embryoblast; this mass of cells will go on to form the embryo. At this stage of development, the inner cell mass consists of embryonic stem cells that will differentiate into the different cell types needed by the organism. The trophoblast will contribute to the placenta and nourish the embryo
