Question (1/8)

The placenta is an organ.

That's right. It's wrong.


It is a joint body, fœto-maternal: it takes two to make it, mom and baby! Seven days after the fertilizationthe egg clings to the uterine wall. It is composed of an embryonic bud and an envelope the trophoblast. Like a tree that takes root, the trophoblast sends ramifications into the walls of the uterus to reach the maternal blood vessels. The placenta is thus made up half from the uterine wall and the other half from the trophoblast. Operational from the beginning, it is fully formed in mid-pregnancy.
