   The membrane, together with its accessories which covers the foetus in the uterus, that established communication including blood supply between mother and foetus.

The placenta develops from the same sperm and egg cells that form the fetus, and functions as a fetomaternal organ with two components, the fetal part (Chorion Frondosum), and the maternal part (Decidua Basailis).
