    It is a biological structure present at the connection of the umbilical cord of the developing foetus to the uterine wall of the mother during pregnancy. It permits close proximity between the maternal and foetal circulations (blood vessels) so that exchange of substances between mother and foetus can occur, i.e. diffusion of glucose, amino acids, fatty acids, oxygen, antibodies, etc to the foetus and of CO2, urea, uric acid and other waste from foetus to mother for elimination by the mother's lungs and kidneys.

    At childbirth, the placenta is normally ejected from the mother as so-called "afterbirth".

    Hope tthis helps!
