The placenta and the hormones of pregnancy
After implantation the embryo needs food and oxygen, and a way to send out its wastes. The placenta does this work, and the umbilical cord joins it to the embryo. The placenta also makes hormones, and with the ovary it keeps the pregnancy going. This lesson explains the structure of the placenta and the work of these hormones.

Parturition and lactation
Birth is controlled by signals from the foetus and the placenta, and by the hormone oxytocin, in a chain that strengthens itself. After birth, the mammary glands give milk, and the first milk is rich in antibodies. This lesson explains the chain of parturition, and the making and release of milk.
