What is the composition of the vessels in the umbilical cord?

• A. One vein with deoxygenated blood and two arteries with oxygenated blood
• B. Two veins with deoxygenated blood and one artery with oxygenated blood
• C. One vein with oxygenated blood and two arteries with deoxygenated blood
• D. Two veins with oxygenated blood and one artery with deoxygenated blood

Answer: (C)

The umbilical cord consists of one vein and two arteries. The correct understanding of this structure is critical for various aspects of fetal development and monitoring during pregnancy. The vein in the umbilical cord carries oxygenated blood from the placenta to the fetus, which is vital for fetal development, providing the necessary nutrients and oxygen. This is contrary to typical arterial systems where arteries carry oxygenated blood; however, in this case, the unique function of the umbilical vein makes it crucial for the fetus's health. The two arteries, on the other hand, transport deoxygenated blood from the fetus back to the placenta. This blood is relieved of carbon dioxide and other waste products, which are expelled by the placenta. Understanding this composition is fundamental for healthcare practitioners involved in maternal-fetal medicine, as it guides assessments during ultrasounds and fetal heart rate monitoring, as well as determining the health and well-being of the fetus throughout gestation.
