Fetus – The developing baby is seen inside the amniotic sac, surrounded by amniotic fluid that cushions and protects it.
Umbilical Cord – Connects the fetus to the placenta, carrying oxygen and nutrients from the mother to the baby and removing waste products.
Placenta & Placental Villi – Located at the top of the uterus, the placenta attaches to the uterine wall. Placental villi increase surface area for nutrient and gas exchange between mother and fetus.
Uterine Musculature & Blood Vessels – The thick muscular walls of the uterus (myometrium) provide structural support, while blood vessels supply oxygen-rich blood.
Intervillous Space – The area where maternal blood flows around the chorionic villi, facilitating exchange of oxygen, nutrients, and waste.
Decidua Basalis – The part of the endometrium where the placenta is anchored.
Decidua Parietalis – The lining of the uterus not directly involved with the placenta.
Chorionic & Amniotic Cavities – The chorion (outer membrane) and amnion (inner membrane) form protective layers around the fetus. The amniotic cavity is filled with amniotic fluid.
Fused Chorion and Amnion – As pregnancy progresses, these two membranes fuse, enclosing the fetus.
Amniotic Sac – A thin but strong sac that surrounds the fetus, holding the amniotic fluid.
Uterine Cavity & Glands – The uterine cavity houses the fetus, and glands in the lining produce secretions that support pregnancy.
Cervix – The lower part of the uterus that connects to the va**na. It is sealed with a cervical mucus plug during pregnancy to protect against infections.
Va**na & Fornices (Anterior & Posterior) – The birth canal, which also serves as the passageway for menstrual flow and in*******se.
This image is an excellent representation of the maternal-fetal interface and the protective systems that support fetal growth and development throughout pregnancy.
