What is the primary function of the umbilical arteries?

• A. Transport oxygenated blood to the fetus
• B. Carry deoxygenated blood away from the fetus
• C. Provide nutrients to the placenta
• D. Facilitate waste removal from the fetus

Answer: (B)

The primary function of the umbilical arteries is to carry deoxygenated blood away from the fetus. In the fetal circulation system, the umbilical arteries transport blood that has low oxygen content from the fetus back to the placenta. In the placenta, this blood can exchange carbon dioxide and waste products for oxygen and nutrients. This function is vital for maintaining the fetus’s overall health, as it ensures that any waste products generated by the fetal metabolism are effectively removed. Understanding the role of umbilical arteries is crucial when studying fetal physiology and how nutrients and oxygen are supplied to the developing fetus through the placenta. The other options listed do not accurately represent the function of the umbilical arteries. Transporting oxygenated blood is primarily the function of the umbilical vein, while nutrient provision and waste removal are more complicated processes that involve the overall interaction between the placenta and fetal circulation rather than the umbilical arteries alone.
