Explanation:
So, you may remember that the placenta is the composite structure of embryonic and maternal tissues that supplies nutrients to the developing embryo. The placenta is a unique organ, found only in mammals, that allows the mother to provide a very large amount of nutrients to her offspring for an extended period of time before they are even born.
The placenta serves as an interface between the mother and the developing fetus and has three main jobs:
Attach the fetus to the uterine wall
Provide nutrients to the fetus
Allow the fetus to transfer waste products to the mother's blood
