The human embryo is surrounded by various structures inside the uterus that support its development. The diagram below shows the embryo's location and the relevant parts of the female reproductive system.
Step 1: Key structures of the diagram.
1. Amniotic sac: This fluid-filled sac surrounds the developing embryo and provides protection.
2. Placenta: The placenta is the organ that forms on the uterine wall, providing nutrients and oxygen to the embryo while removing waste.
3. Umbilical cord: It connects the embryo to the placenta and carries blood with nutrients to the fetus and removes waste.
4. Uterine wall: The thick layer of tissue that provides support for the embryo, as it is attached to the uterine lining.
5. Embryo: The developing organism within the amniotic sac, starting from a zygote and undergoing stages of development.
Final Answer:
The diagram illustrates the embryo inside the human uterus, including key features like the amniotic sac, placenta, umbilical cord, and uterine wall.
