An illustration depicting the internal anatomy of the placenta, showcasing its role in the exchange of nutrients between maternal and foetal blood. The placental produces hormones such as oestrogen, progesterone and corticotrophin-releasing hormone (CRH) that circulate in the mother's blood to regulate pregnancy. A cross-sectional view of the placenta shows the maternal portion (left side) exchanging blood with the foetal portion (right side). An inset of a chorionic villus show how nutrients and antibodies can be transferred and delivered to the baby via the umbilical vein. | |
