Final answer:
Implantation occurs in the uterus, not in the umbilical cord. The umbilical cord connects the fetus to the placenta and is composed of two arteries and a vein for the exchange of oxygen, nutrients, and waste.
Step-by-step explanation:
False: Implantation does not occur in the umbilical cord. Instead, implantation is the process where the fertilized egg attaches itself to the lining of the uterus. The umbilical cord is a vital part of the fetal development process, as it is the conduit that connects the fetus to the placenta.
The placenta plays a critical role in transferring nutrients and oxygen from the mother to the fetus and expelling waste products from fetal blood. The umbilical cord contains two umbilical arteries that carry deoxygenated and waste-laden blood from the fetus to the placenta, while one umbilical vein carries oxygen-rich blood from the placenta back to the fetus.
