placenta

n. organ that forms on the wall of the uterus during pregnancy and carries nourishment to a growing fetus while removing waste products

The placenta is an ephemeral (temporary) organ present in placental vertebrates, such as some mammals and sharks during gestation (pregnancy). 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).
