What is the primary function of the umbilical cord during fetal development?

• A. To supply blood to the brain
• B. To connect the fetus to the placenta
• C. To form the neural tube
• D. To provide genetic information

Answer: (B)

The primary function of the umbilical cord during fetal development is to connect the fetus to the placenta. This connection is crucial as it facilitates the transfer of essential nutrients and oxygen from the mother to the developing fetus, while also allowing for the removal of waste products from fetal circulation. The umbilical cord contains blood vessels that carry this vital exchange, ensuring the fetus receives the necessary resources for growth and development throughout pregnancy. This connection to the placenta is a key aspect of fetal survival and health, as without it, the fetus would be unable to receive the nourishment it requires for its growth and there would be no efficient way to eliminate waste. The umbilical cord is therefore central to the entire process of prenatal development.
