How many arteries and veins are typically found in a newborn's umbilical cord?

• A. 1 artery, 1 vein
• B. 2 arteries, 1 vein
• C. 2 veins, 1 artery
• D. 3 arteries, 1 vein

Answer: (B)

In a typical newborn's umbilical cord, there are two arteries and one vein. This configuration is crucial for fetal circulation, as the two arteries transport deoxygenated blood from the fetus back to the placenta, while the single vein carries oxygen-rich blood from the placenta to the fetus. This arrangement ensures that the developing fetus receives the nutrients and oxygen necessary for growth while simultaneously removing waste products. The presence of two arteries and one vein is a key aspect of normal fetal anatomy, and any deviations from this standard can indicate potential complications or congenital abnormalities. This understanding underscores the importance of recognizing the typical structure of the umbilical cord in medical practice.
