    Study Notes

    Placenta Structure and Function

    • The chorionic plate is the topmost layer of the placenta, facing the maternal side, and facilitates the exchange of oxygen, nutrients, and waste products between the mother and fetus.

    Umbilical Cord Attachment

    • The umbilical cord attaches to the center of the fetal surface of the placenta.

    Basal Plate Function

    • The basal plate is the layer of the placenta adjacent to the maternal uterine wall, and it plays a crucial role in anchoring the placenta to the uterus.

    Amniotic Membrane Function

    • The main function of the amniotic membrane is to produce amniotic fluid, which cushions the fetus and allows for movement during pregnancy.

    Chorionic Plate Role

    • The chorionic plate helps regulate the exchange of substances between the maternal and fetal bloodstream.

    Maternal Blood Flow

    • The cytotrophoblast layer of the chorionic plate allows maternal blood to flow into the intervillous space, enabling the exchange of oxygen and nutrients with the fetus.

    Umbilical Cord and Placenta

    • The umbilical cord is attached to the center of the fetal surface of the placenta, allowing for the exchange of oxygen, nutrients, and waste products between the mother and fetus.
