What structure connects the placenta to the fetus during human development?
A
Chorion
B
Amniotic sac
C
Umbilical cord
D
Yolk sac
Verified step by step guidance1
Understand the role of the placenta in human development: The placenta is an organ that facilitates the exchange of nutrients, oxygen, and waste products between the mother and the developing fetus.
Identify the structure that physically connects the fetus to the placenta: This structure must allow the transfer of blood and nutrients between the two.
Learn about the umbilical cord: The umbilical cord is a tube-like structure containing blood vessels (two arteries and one vein) that connects the fetus to the placenta, ensuring the exchange of essential substances.
Differentiate the umbilical cord from other structures: The chorion is part of the fetal membrane, the amniotic sac surrounds the fetus to provide protection, and the yolk sac is involved in early blood cell formation but does not connect the fetus to the placenta.
Conclude that the umbilical cord is the correct structure connecting the placenta to the fetus during human development.
